David Stanley Knight, 80, of Shreveport, Louisiana, died March 29, 2026, after an eight-month battle with bile duct cancer. He was born June 22, 1945, in Jefferson, Texas. He graduated from Jefferson High School and later received a Bachelor of Science degree in Biology from Stephen F. Austin State University. While attending Stephen F. Austin, he met the love of his life, Kathie Lindsay, and they married shortly after graduation in 1968. He served in the United States Air Force, attaining the rank of First Lieutenant. After his military service, he returned to school at Tulane University, where he earned his Ph.D. Following his graduation from Tulane, the family moved from New Orleans to Shreveport, where David worked at the LSU Medical School as a professor in the Department of Cellular Biology and Anatomy for over 30 years, retiring in 2011. 

In his free time, he enjoyed reading, watching classic films, listening to music, and woodworking. In his later years, he especially enjoyed spending time at the Red River Wildlife Refuge in Bossier City. He was also a talented artist who created many sketches and watercolor paintings. David and Kathie loved to travel and especially enjoyed visiting lighthouses. David was a wise man with a gracious heart. 

He was preceded in death by his father, Henry Roberson Knight; his mother, Willie Ethel Trice Knight; and his beloved wife of 54 years, Kathie Ann Lindsay Knight. 

He is survived by his two sons, David Stanley Knight, Jr. and Steven Michael Knight (Tina); his two grandchildren, Kaylee Knight and Brittany Welch (Josh); and his three great-grandchildren, Corbin, Evelyn Grace, and Oaklyn. He is also survived by his sisters, Robbie Fortune, Ellen Stephenson (Barney), Anne Turner (Gaylon), and Susie Briscoe (Bobby); and his brother, Dan Knight. 

A private memorial will take place in Jefferson, Texas, at a later date with family and close friends.

David’s last words were to wake up every day with a smile and to always be kind to one another.
