How a tuberculosis diagnosis transformed a medical student into a celebrated existentialist novelist

In short: Walker Percy abandoned a promising career in medicine after contracting tuberculosis, a forced convalescence that led him to the works of Kierkegaard and Dostoevsky. This shift sparked a literary career defined by existential inquiry, eventually earning him a National Book Award and cementing his legacy as a profound Southern intellectual.

Born in 1916, Walker Percy was marked by early tragedy; both of his parents died by suicide, leaving him to be raised by his cousin, the poet William Alexander Percy. Though he earned an M.D. from Columbia University in 1941, his medical path was cut short by a tuberculosis diagnosis at Bellevue Hospital in 1942. While recuperating in sanatoriums, he abandoned his clinical ambitions, finding solace in existentialist philosophy and a newfound Catholic faith, to which he converted in 1947.

Percy’s fiction, beginning with his 1961 debut The Moviegoer, explored the alienation of modern life through characters struggling with spiritual loneliness. His work often bridged the gap between scientific rationalism and Judeo-Christian ethics, a theme he expanded upon in nonfiction works like The Message in the Bottle. His literary influence was significant, helping to shift Southern literature toward themes of estrangement and the complexities of the post-war world.

Beyond his own writing, Percy was a mentor and cultural force. He was instrumental in the posthumous publication of John Kennedy Toole’s A Confederacy of Dunces, which later won a Pulitzer Prize. In his final years, Percy faced prostate cancer with a stoic resolve, participating in experimental drug trials at the Mayo Clinic not for his own benefit, but to aid future patients. He died in 1990, shortly after becoming a Benedictine oblate, leaving behind a body of work that continues to challenge the limits of modern science.
