The passing of a beautiful mind May 6, 2022; Paul Stallings Mostert Born to Johannes Frederick Theobald and Lucy (Stallings) on November 27, 1927 in Morrilton, Arkansas. He and his siblings spent life with their mother traveling in their car during the great depression. His childhood years were spent in Kentucky, after spending time in the south and Midwest he returned to Lexington in the early 1980’s.


Preceded in death by his wife, Barbara (DeMarcus) Mostert and siblings, John F.T. (Jack) Mostert, Roberta Mostert Soyers, and Mary Mostert as well as his half-brother, Dirk Mostert.


Paul is survived by his half-brother, Nico Mostert, South Africa; children, Theodore Mostert (Zandi), Baton Rouge, LA, Richard Mostert, New Orleans, LA; Kathleen Baker (Ben), Ft. Myer, FL; Kristina Rivotto (Tony) Shawnee, KS ; stepchildren, Cynthia Manson (Ken), Baton Rouge, LA and Lisa DeMarcus, Lexington, KY, 10 grandchildren and 11 great grandchildren.


Prior to embarking on his educational and professional journey, Paul served in the U.S. Navy until end of WWII. Paul received his B.A. in Mathematics from Rhodes College in 1950, followed by M.S in Mathematics from University of Chicago (1951) and received his Ph.D from Purdue University (1953). Paul was inducted into Rhodes College Bellingrath Society.


Paul taught mathematics in various positions over the years from research instructor to professor at Purdue, Professor and Chairman at Tulane and University of Kansas; University of Tübingen (Germany), Institute for advanced Study at Princeton and during retirement serving as visiting professor at University of Kentucky.


As co-founder of The Semigroup Forum he served in multiple roles between 1969-1987 and spoke at a myriad of conferences and symposia meetings. He contributed to numerous written articles and publications, such as the Journal of Equine Veterinary Sciences, the American Journal of mathematics, the Czechoslovak Mathematical Journal and the College Mathematics Journal. Paul directed several doctoral dissertations and received worldwide recognition for his work including Who’s Who of America; Who’s Who of the World of Mathematics; Albert Nelson Marquis Lifetime Achievement Award.


Paul became interested in horses when his daughters were involved in showing hunter/jumpers. This led to his desire to figure out what makes a horse run fast and how to build a better racehorse. This passion led to the development of 14 software programs using mathematical models of the biomechanics of racehorses which produced the breeding of two Kentucky Derby winners and numerous champions and Grade-I or Group-I winners in America, Britain, Europe and South Africa. Much of the technology developed was further applied to other animal applications, such as tracking wildlife as well as human sports and medical practices for 3D video camera control for motion and non-contact eye recognition systems. The technology has been applied to the US Olympic training center for athletes to view form for performance improvement as well as for sports replay and more efficient design for artificial limbs and medical braces. Paul received a Small Business Research Grant from the National Science Foundation and presented many grants from the Ford Foundation, Office of Naval Research, Tulane University and University of Kentucky.


Paul held positions with a variety of other organizations and institutions. Serving as a co-principal investigator and scientific director with i2i Technologies from 2009 to 2010, he was previously president of the EQUIX Research Corporation from 1985 to 2003 and EQUIX Biomechanics from 1989 to 1997 and as consultant with the Mostert Group, Mostert Seales Research Company, LLC, and EquiMost.


Paul had a love of writing poetry and would share specially written notes to family members for special occasions. Paul enjoyed traveling, hiking – especially to see waterfalls and kayaking. Dance was another passion and he and his wife Barbara (d. July 2021) performed as the grandfather and grandmother in the Nutcracker with the Lexington Ballet as well as wining several dance awards and danced into their 90’s.

Milward Funeral Directors are entrusted with Mr. Mostert's arrangements. A graveside service is scheduled for Friday, May 13th at 11:30 am at Lexington Cemetery.

In lieu of flowers, donations to Rhodes College or to the educational institution of your choice are appreciated.

Uncle Paul was always kind with a big smile and crinkly eyes. My Dad Jack, spoke respectfully of his little brother. They had many adventures together as boys. Interesting that they passed within weeks of each other. Close brothers to the end.

My Dad also had a wonderful sense of humor and love for ice cream! I had the honor of going with him to visit his younger sister and her funeral. At 89 years young he wanted to hike Bridal Falls. So we did and enjoyed ice cream after
