Dr. Peter John Flippin was born in Oakland, Tennessee, and graduated in 1897 from the Memphis Hospital Medical College, later the University of Tennessee Medical School. For five decades he provided medical care to white and African-American citizens of Rosemark and surrounding communities, and the University of Tennessee honored him for fifty years of medical service. Known as “Doc” Flippin, he customarily extended credit to members of the community, forgoing payment until after the crops were harvested or accepting whatever payment they could afford. He was one of the leading citizens of the community, serving as a successful farmer, church elder, bank vice-president, and member of numerous organizations. He delivered over 1300 babies in northern Shelby and southern Tipton Counties, and many of their descendants still live in the area. He retired from medical practice in 1947 and died in Rosemark in 1950, leaving a legacy of service to the people of the community.
