Oliver Vanetta Lynn, Jr., commonly known as Doolittle Lynn was an American talent manager and country music figure, known as the husband of country music legend Loretta Lynn. Over the course of their often-tumultuous 48-year marriage, Lynn was instrumental in developing his wife's musical talent and country music career, purchasing her first guitar, lining up her first radio appearances, and serving as her de facto talent manager for many years. Lynn was also the President of Loretta Lynn Enterprises, Inc., a company formed in 1973 to take care of Lynn’s businesses.
In addition to his ongoing support for his young wife's career, Lynn's relationship with his wife was described in the following: "[He] thought I was something special, more special than anyone in the world, and never let me forget it... Doo was my security, my safety net". He was also known to be violent, an alcoholic, and a womanizer who was a somewhat reluctant participant in his wife's life as a country music celebrity. Nonetheless, he was a central figure in many of his wife's hits, including "Fist City", "The Pill", "Don't Come Home A-Drinkin'", and "You Ain't Woman Enough".
