The conservative think-tank David Horowitz Freedom Center on Tuesday announced that its founder, David Horowitz, died at the age of 86. 

The center revealed that Horowtiz, a renowned journalist and author, died after a "lengthy battle with cancer."

Horowitz was often referred to as a "red diaper baby," having been raised by parents who were in the Communist Party. He eventually became a dynamic conservative activist and author. 

"Rest in Peace to my father [David Horowitz]," his son Benjamin Horowitz posted to X. "We love you Dad."

Benjamin Horowitz, one of the co-founders of the venture capitalist firm Andreessen Horowitz, shared an obituary that highlighted his father's wide-ranging career, which included multiple books, the creation of the center, and an endorsement of President Donald Trump.

"In the end, David helped countless people and expended every fiber of his being pushing society towards freedom," the obituary reads. "He may not have saved the world, but he most certainly made it a better place – especially for us. He was our super hero and we will love him forever."

He is survived by his sons Ben Horowitz, Jonathan Horowitz, and daughter Anne. His other daughter Sarah Rose died in 2007.
