Dr. Rhea Seddon, Reaching for the Stars 2021

Dr. Rhea Seddon, Reaching for the Stars

March 17, 2021 – As we continue to celebrate Women’s History Month, we are spotlighting some of the women featured throughout our museum and heritage park who have changed history, made scientific breakthroughs, overcome seemingly insurmountable adversity and inspired the generations after them to see beyond.

One of two NASA flight suits on display in Discovery Park of America’s Moon Dome at STEM Landing was worn by former astronaut, Dr. Rhea Seddon. In 1978, Dr. Seddon was selected as one of the first six women to enter the Astronaut Program and would go on to serve a total of 30 days in space as  mission specialist on Space Shuttle flights in 1985 and 1991 and as a payload commander in charge of all science activities on her final flight in 1993.

After a 19 year career with NASA, she went on to become the assistant chief medical officer at Vanderbilt University Medical Center in Nashville. There she led an initiative to improve patient safety, quality care and team effectiveness by use of an aviation-based model of Crew Resource Management.

She is a national speaker and award-winning author who today encourages young and old alike to reach for the stars. Dr. Seddon, a Murfreesboro, Tennessee-native now living in Nashville, was inducted into the Tennessee Aviation Hall of Fame in 2005, the Astronaut Hall of Fame in 2015, and the Tennessee Women’s Hall of Fame also in 2015.

Discovery Park of America Provides Learning Tools for Local Preschool 2021

Discovery Park of America Provides Learning Tools to Local Preschool

March 11, 2021 – At Discovery Park of America, our mission is to inspire children and adults to see beyond. A big part of that mission includes working alongside organizations in our community to encourage others to grow and consider new ideas regardless of age or education.

Al Wright, Discovery Park’s director of maintenance, recently constructed learning tools for the Miles Head Start preschool in Union City, Tennessee. He carved dog treat bones for a “Pet Study” lesson that taught numerous objectives including sorting, classifying, counting, using fine motor skills to paint and comparing. This activity offered the young students a fun and interactive method of learning new skills that they will use in their everyday lives for years to come.

Wendi Wright, a teacher at Miles Head Start, said, “I truly appreciate the time Discovery Park of America took to help my students grow in so many areas while still having fun.”

Community engagement projects like this one are what Discovery Park’s  founders, Robert and Jenny Kirkland, envisioned when they built this one-of-a-kind, transformational museum and heritage park right here in Northwest Tennessee.

Dr. Nadia Shakoor, Pioneer in Digital Agriculture 2021

Dr. Nadia Shakoor, Pioneer in Digital Agriculture

 March 10, 2021 – As we celebrate Women’s History Month at Discovery Park, we are making people aware of the women who have changed history, made scientific breakthroughs, overcome seemingly insurmountable adversity and inspired the generations after them to see beyond.

Dr. Nadia Shakoor is a senior research scientist at The Donald Danforth Plant Science Center in St. Louis, Missouri, and a pioneer in digital agriculture. She and her team are developing FieldDock, an integrated smart farm system that will collect and analyze real-time data from fields, allowing for effective tracking of crop performance.

We expect the FieldDock to transform the way crop scientists, breeders and farmers interact with agricultural technology and have a significant impact on the sustainability of food production.

While working on the FieldDock project, Dr. Shakoor needed a data-collection instrument that did not exist yet — so she invented one. The PheNode is a 100 percent solar-powered device with environmental sensors that monitor the soil, temperature, humidity, air pressure, wind speed, wind direction, rainfall and more for researchers. Automated systems like the FieldDock will pioneer breakthrough for rapid advancement in digital agriculture and play a pivotal role in farms of the future. An example of Dr. Shakoor’s PheNode is on display in Discovery Park’s “AgriCulture: Innovating for Our Survival” exhibit in the Simmons Bank Ag Center.

Charles Henry Turner: Entomologist 2021

Charles Henry Tuner: Entomologist

Feb. 18, 2021 – In Discovery Park’s newly established permanent exhibit, “AgriCulture: Innovating for our Survival, over 10,000 complex, creative and intelligent beings reside in a wooden and glass chamber in the building’s northeast corner. There are eight living species of honeybee in this chamber, and each of them are brilliant, efficient and incredibly structured in their behavior and interactions.

However, this was not always believed to be the case.

For millennia, naturalists assumed that insects were essentially mindless – incapable of complex thought, learning, recognizing patterns or even seeing color. For this reason, little was done to develop the honey industry in the way of altering a colony’s behavior to increase production.

This changed around 1910 with the release of a number of scientific publications by St. Louis-based scientist Charles Henry Turner.

Turner was born in Cincinnati in 1867, graduated valedictorian from Gainesville High School and earned a bachelor’s degree and a master’s of science in biology from the University of Cincinnati. Despite his innate brilliance, experience and education, Turner faced an obstacle in his search for employment that, in the late 19th century, seemed impossible to overcome – his race. Turner went on to become to the first African American person to receive a Ph.D. from the University of Chicago in 1907, but upon seeking employment at an esteemed university, still faced racism and dismissal of his accomplishments. Turner became a high school science teacher at Sumner High School in St. Louis in 1908 and remained there until his retirement in 1922.

Nevertheless, over the course of 30 years, he published over 70 scientific papers, many of which pertained to the behavior of insects. Turner’s work essentially formed the foundation for entomologists for the coming century. Turner was likely the first black entomologist to be published in the United States, as well as the first black scientist published in the journal Science.

Turner is perhaps most well-known for his work with honeybees, detailing in a 1910 paper how bees in his independent study had reacted to various colored disks, showing complex thought processes and color vision.

As we celebrate Black History Month at Discovery Park, we are making people aware of the contributions of black scientists, engineers, artists, and other great minds who have shaped the disciplines represented in each of our museum and heritage park’s galleries.

Volunteer of the Year: Sue Ellen Morris 2021

Volunteer: a person who voluntarily undertakes or expresses a willingness to undertake a service

Jan. 14, 2021 – Discovery Park is pleased to name Sue Ellen Morris as the 2020 Volunteer of the Year. Volunteers are important to Discovery Park. They enhance our ability to implement our mission by offering their knowledge and expertise in a variety of ways.

When Sue Ellen started volunteering in early 2020 at Discovery Park, she soon realized one of her favorite things was sharing information about the park with first-time guests. “I really enjoy meeting the people that visit from around the world,” said Sue Ellen. “I like hearing their stories and watching the children’s reactions when they walk through the doors and see the giant cave bear or the dinosaur skeletons. Some are frightened by the bear and others want to hurry to see if it’s real.”

“Of course, 2020 was a tough year for all of us,” said Scott Williams, Discovery Park president and CEO. “Rounding the corner and seeing Sue Ellen sitting there with her mask on, ready to welcome guests, always made me feel a little happier.”

Sue Ellen received an etched serving board handmade by Discovery Park volunteer John. R. Hall for her dedication to Discovery Park of America.

Get to Know the 2020 Volunteer of the Year

Born in Hickman County, Ky., to Raymond and Estelle Morris, Sue Ellen grew up on the family farm with her two sisters, Gina Lou and Ruth Ann. She was always helping out on the farm, driving tractors and planting soybean, corn and wheat. Growing up, she was also an avid reader and volunteered at the library in Clinton, Ky. She loved reading books about places around the world that she never dreamed a little girl from a small town in Kentucky would visit. Little did she know what was to come.

She attended Murray State University and received her undergraduate degree in English with a minor in history. Sue Ellen then decided to pursue law school and attended the University of Tulsa. After she graduated with her law degree, she realized that the big city life and the cold were not for her. She missed her family, the warmer weather and the greenery of her hometown. So, she packed everything up and headed back home to begin her career as a lawyer at Roberts, Bugg and Morris in Clinton, Ky.

Once her career took off as a partner in the law firm, she remembered the books she read as a little girl about all the exotic places around the world she wished she could visit. Sue Ellen convinced her sister, Ruth Ann, to be her travel partner and they started exploring the amazing places she had only read and dreamed about visiting. She and her sister visited places all around Europe, including Ireland, Great Britain and Italy. Their furthest adventure to date has been to New Zealand. They have also met friends that they now travel with on their adventures.

“She loved reading books on places around the world that she never dreamed a little girl from a small town in Kentucky would visit. Little did she know what was to come.”

“My favorite place that I have visited is Rome,” said Sue Ellen. “The city, the history, the food and the people make it one of the most interesting and culturally rich places to visit. We have found the best gelato place in Rome and have to visit it every time we are there.”

Sue Ellen and her sister had to put their next adventures on hold when COVID-19 hit. “We are big cruisers and had two cancelled, one in 2020 and one in 2021, but we have a Celebrity Cruise planned later this year that starts in Venice and ends in Rome. We are really hoping we get to experience this trip.”

Since international travel is paused for now, we asked Sue Ellen where her favorite place to visit is in the United States. “I really like to travel to the Smoky Mountains. We rent a cabin, take hikes and just relax.” She already has a condo booked in April to hunt for spring wildflowers in Sevierville with her travelling buddies.

“I like hearing their stories and seeing the children’s reactions when they walk through the doors and see the giant cave bear or the dinosaur skeletons. Some are frightened by the bear and others want to hurry and touch it to see if it’s real.”

She still practices law part-time, but within the next couple of years, she wants to have something more she can do to give back to the community once she completely retires. This volunteer program fits in well with her plans. Plus, Sue Ellen enjoys taking photos of the guests and giving them the information they need to enhance their experience at Discovery Park.

When asked if she recommends others to volunteer at the park, she said, “Yes! This is a great opportunity for retired educators or for anyone who is passionate about sharing knowledge with others.” She also shared her favorite part of the park. “I really enjoy the grounds, and I like to see the transformation of the outdoor foliage that occurs as the seasons change. The grounds staff does an awesome job. I also love the old cars and there are a couple I would love to take home.”

If you or someone you know is interested in joining the volunteer program at Discovery Park, please email Polly Brasher at pbrasher@discoveryparkofamerica.com for more information.

Caterpillar Model Fifteen 2020

Caterpillar Model Fifteen

Nov. 30, 2020 – On Dec. 5, 2020, Discovery Park of America’s newest permanent exhibit, AgriCulture: Innovating for Our Survival, will open to the general public. This eye-opening display will give guests of all ages a better understanding of how food, fuel and fiber get from the farm to consumers and the significance scientific innovation plays in the modern agricultural industry.

While the exhibit will shed light on the latest and greatest in agricultural technology, it will also illuminate the lesser-known history of farm machinery over the last 150 years. This will be accomplished through the inclusion of several machines that have been on display at Discovery Park since its inception as well as a few newcomers – most notably a 1927 Caterpillar Model Fifteen, one of a series of tractors that redefined the American farm.

In 1907, Benjamin Holt, a wheel maker in Stockton, Calif., noted that the soft alluvial soils surrounding the San Joaquin River in California’s Central Valley were often impassible by heavy steam-powered tractors, which sank deep into the ground or became stuck on rolling terrain. Mimicking a technique that he had witnessed in England four years prior, Holt developed a tractor with a system of endless steel platforms, which we now recognize as continuous track, which allowed the weight of the tractor to be distributed across a larger area, causing the machine to float across the surface much like a snowshoe on unconsolidated snow. This design also prevented the tractor from compacting the soil too tightly, which was detrimental to row crops. A photographer hired to document the prototype noted that the machine crawled across the earth like a caterpillar – and thus, the brand was born.

In 1910, Holt purchased the defunct Colean Manufacturing Company facility in Peoria, Ill., a city that would host Caterpillar Inc.’s headquarters until 2017. Holt’s nephew, Pliny Holt, managed the facility in its infancy. After the outbreak of World War I, Holt Manufacturing Company shifted all of its focus away from agricultural equipment to facilitate the production of military equipment, including artillery tractors equipped with continuous track, which many historians have credited as an essential advancement on the Allies’ path to victory in 1918. During the war, C.L. Best Tractor Company, a competitor that Holt had frequently encountered in courtrooms over the previous decade over trademark infringement, took the lead in domestic farm equipment sales. Nevertheless, both companies took massive losses in the recession of 1920-21. In 1925, after 20 years of rivalry and at the urging of investors, Holt Manufacturing Company and C.L. Best Tractor Company merged to form Caterpillar Tractor Co.

The two companies consolidated their product lines to offer only five “crawler” type tractors, including the new company’s first original line – the Caterpillar Model Fifteen. Weighing in at 4,500lbs, the relatively compact and lightweight Model Fifteen was equipped with a four-cylinder gasoline engine employing three forward gears and one reverse.

With the assistance of Robert Weunch, Discovery Park of America acquired the 1927 Model Fifteen in a dilapidated state in 2014 from Robert Lavoie. Union City natives and brothers David and Jeff Ursery began working to restore the piece to its original functionality and charm. The Ursery brothers began by disassembling the tractor to bare parts and determining which parts were salvageable and which would need to be completely rebuilt. Some of the irreparable pieces were milled at local tool and dye shops, while others are parts from newer tractors that have been modified to function on the Model Fifteen. Enough of the original paint remained to formulate a new coat, and faded emblems were deciphered by examining vintage photos and diagrams of tractors from the same production line.

On Nov. 10, 2020, the tractor was delivered to its new permanent location in the Simmons Bank Ag Center by Buddy’s Wrecker Service, where it will inspire children and adults to see beyond their understanding of the American farm for years to come.

The Great Gauge Change of 1886

Nov. 20, 2020 – In May of 1886, the United States was in the midst of what is now known as the Gilded Age. This period was marked by a rapidly developing economy and the cultural reunification of the North and South. Over the course of 20 years, the average wage for an industrial worker in the U.S. nearly doubled, and the standard of living for American families skyrocketed above that of most European countries. The economic development that epitomized this era rode in on trains – innovative, perpetually evolving trains. A uniform and efficient railroad system became a pivotal asset to the nation, and the time had come to work out its antiquated quirks.

Over 60 years earlier, in 1827, Baltimore & Ohio Railroad had been commissioned with the purpose of transporting goods being shipped along the Ohio River in the West to the port at Baltimore in the East. As America’s first railroad, the company set the standard for railways in the North by copying British railways in formatting track. The rails were placed 56.5 inches apart – a measurement that had been decided on by George Stephenson, a British engineer known as “the Father of Railways.” A separate railroad, the South Carolina Canal and Railroad Company, got its start only 9 months later in Charleston, South Carolina. To accommodate the movement of larger cotton bales, the founders of South Carolina C&R decided on a rail spacing, or “gauge,” of 60 inches – exactly 5 feet.

As the years went on, the 56.5 inch gauge became the standard for railroads hailing from the North, while Southern railways followed South Carolina’s suit in standardizing the 60-inch gauge. These were not the only gauges present in the U.S. railroad system. In fact, by 1871, there were at least 23 different gauges in use by American railroads. Since trains would have to be specially formatted and equipped to run on a certain width of track, this was a major issue by the Gilded Age reform. Trains would have to be unloaded and the freight moved to another train at the interchange in order to make its full transit. In fact, North Carolina adopted the Stephenson gauge (Northern system) in order to make trade with the North easier and drew massive amounts of commerce away from surrounding Southern states as a result.

On February 2, 1886, the operating officers of the South’s major railroads met at Kimball House in Atlanta to discuss a shift to the Stephenson gauge. While some advocated passionately for the full transition, the final decision was to adopt a 4-foot-9 inch gauge – 3 inches narrower than the Southern gauge, but still a half inch wider than the Stephenson gauge. This miniscule difference allowed for most engines formatted for the Stephenson to still traverse the tracks, while also being wide enough for use by the Pennsylvania Railroad, a unique Northern Railroad with a 4ft9in gauge which had many interchanges with Southern rails. It was decided that on May 31st and June 1st of that year, in just two days, tens of thousands of railroad laborers across the South would pull up some 11,500 miles of rail and move them inward. Only one side would need to be moved, so it was decided that the western or northern side of each track would be shifted 3 inches.

The four-month preparation period allowed for special wheels to be made for engines and cars that could simply be turned around on their axles on the transformation day to fit the new track. When May 31st came, hundreds of workers hit the ground reversing the wheels on thousands of cars and engines, while thousands more workers quickly plucked railroad spikes on the 11,500 miles of track and shifted them inward by 3 inches. This daunting task was made considerably more efficient with the use of a special caliper known as a railroad gauge. Instead of measuring the distance between the rails every few feet, the workers could simply slide the caliper (like the one found in Discovery Park’s Depot), which had a set length of 4ft9in, down the track and confirm its uniformity.

On June 1st, after the noisiest 36 hours the South ever experienced, the last spike was hammered in. Over the next several decades, regular maintenance of tracks eventually shifted all railroad tracks in the South to the Stephenson gauge of 4ft 8.5in. Nevertheless, the Great Gauge Change of May 31st and June 1st, 1886 remains one of the greatest feats of engineering in world history, let alone the most magnificent coordinated effort in the Southern United States prior to telecommunications.

Side note: The day after the transition, June 2, 1886, President Grover Cleveland, who was 49, married college student Frances Folsom in the Blue Room of the White House. Cleveland had been the executor of her father’s estate and oversaw her upbringing. Nevertheless, at just 21 years old, she became one of the most beloved first ladies in American History. This was a busy week in American history, indeed!
