David Horowitz, the outspoken conservative commentator and author, passed away this week at the age of 86 after a long battle with cancer.
His name may be familiar for his fierce political views and the think tank he founded, but Horowitz’s story is one of transformation—a journey from the radical left to the frontlines of American conservatism.
Whether you agreed with his ideas or not, his voice helped shape the conversation on politics, activism, and freedom in America.
Born in Queens, New York, in 1939 to leftist parents, Horowitz began his career as a committed Marxist.
He earned degrees from Columbia and UC Berkeley and quickly became a central figure in the New Left movement of the 1960s.
He edited the influential radical magazine Ramparts and was deeply embedded in progressive activism.

But by the late 1970s, disillusionment set in.
The turning point, he later said, was the murder of his friend Betty Van Patter—a crime he believed was tied to the Black Panther Party.
That tragedy, along with growing concerns over political violence, caused Horowitz to re-examine his beliefs.
By the 1980s, he had become a vocal conservative.
He didn’t just change sides—he challenged his former allies with unrelenting criticism, becoming one of the right’s most provocative thinkers.
Horowitz chronicled his ideological shift in his memoir Radical Son, widely read across the political spectrum.
Over the years, he published more than 20 books, including The Professors and Unholy Alliance, aimed at exposing what he viewed as the dangers of left-wing extremism in academia and politics.
In 1988, he founded the David Horowitz Freedom Center, which became a hub for conservative commentary and activism.
The center publishes FrontPage Magazine, runs student-focused programs, and champions free speech on college campuses.
Those who knew Horowitz personally describe a man deeply committed to his family.
He is survived by his wife, April Mullvain; sons Benjamin and Jonathan; and daughter Anne.
His daughter Sarah Rose passed away in 2008, a loss he carried with him for the rest of his life.
His son, Benjamin Horowitz—co-founder of the venture capital firm Andreessen Horowitz—shared a heartfelt tribute recalling a moment when his father, hospitalized and unwell, was still excited to speak with former President Trump over the phone.
“He may not have saved the world,” Benjamin wrote, “but he most certainly made it a better place—especially for us.”
David Horowitz was not one to avoid conflict.
His critics accused him of sowing division, while his supporters hailed him as a defender of truth and free speech.
He often focused his energy on higher education, arguing that universities had become dominated by leftist ideology and needed balance.
Regardless of where you stand politically, his life raises timeless questions about conviction, change, and the courage to speak out—especially when doing so means leaving behind the comfort of familiar ground.
For many readers of The GrayVine, Horowitz’s life reminds us that change is always possible.
He stood firm in his beliefs—first on the left, then on the right—and challenged others to do the same, even when it meant standing alone.
His story is a testament to intellectual curiosity, personal accountability, and the complex journey of finding one’s voice.
