Eduard Kuznetsov has died. He was born in 1939. He was a prominent Soviet-era dissident and former Prisoner of Zion who endured imprisonment for anti-Soviet activities. He died Sunday at the age of 85.

Born to a Jewish father and a Russian mother, Kuznetsov established himself as a journalist, writer and editor before his activism led to his first arrest by Soviet authorities in 1961. He served seven years in prison for publicly reading protest poetry and anti-regime literature in Moscow’s central square.

In June of 1970 after being denied permission to leave the country, Kuznetsov joined fellow activist Mark Dymshits in a bold attempt to hijack an empty aircraft bound for Israel. The escape plan failed and both men were sentenced to death. Their sentences were later commuted to 15-year prison terms following intense international pressure, while Kuznetsov’s wife received a 10-year sentence.

Kuznetsov finally gained his freedom in 1979 through a US-negotiated prisoner exchange that released him and four other dissidents. He subsequently immigrated to Israel.

His daughter Anat Zalmanson-Kuznetsov shared an emotional tribute on Facebook: “At 1:00 A.M., Eduard Kuznetsov, the man, the legend and my father, passed away. I can’t write these words without breaking into tears.”

She recounted a meaningful moment from 2018 when they shared the stage, where he received recognition for his contributions to Russian-language journalism in Israel. “I knew this was a defining moment in my relationship with my father, one I would return to again and again throughout my life,” she wrote. Despite his reluctance to accept the honor, claiming, “I don’t deserve it. I haven’t been involved in journalism for many years,” she insisted on his worthiness.
