Play Boy founder Hugh Hefner was in failing health for years, and he steadily deteriorated in the final months of his life.
This picture was taken in January … inside the Playboy Mansion. Although Hugh was frail, using a walker to get around, he still hosted movie nights and invited people over.
TMZ reported … Hefner got a back infection 2 years ago and that became the linchpin for a variety of ailments that ultimately led to his death.
Hugh Hefner died Wednesday night at age 91.
