Owner of nightclun, Studio 54 has passed on after he took his life by assisted su*cide in Switzerland.
Fleischman, 82, was unable to walk and his speech was impaired after getting sick in 2016.
Doctors couldn’t diagnose his condition.
"I can’t walk, my speech is f–ked up, and I can’t do anything for myself," he told The Post last month.
"My wife helps me get into bed and I can’t dress or put on my shoes. I am taking a gentle way out. It is the easiest way out for me."
Owning Studio 54, Fleischman partied with the biggest celebrities.
"I liked to be high. So I would do drugs and drink. Possibly, this [health condition] is because I drank a lot and did drugs," he told The Post.
After suffering for years, Fleischman decided to travel to Switzerland and take a lethal dose of barbiturates.
Former business partner, Daniel Fitzgerald told BBC News that Fleischman died following assisted su*cide.
Fleischman worked with the nonprofit Dignitas, which launched in 1998 and is devoted to helping people commit su*cide when their health is failing. Dignitas members reviewed his medical records and had conversations with him.
"The more I think about it, the more I want to do it," Fleischman said. "I am flying direct to Zurich from LA. There will be no last party."
