Lyndon LaRouche Jr. — the noted conspiracy theorist who ran for president eight times, once from federal prison — died earlier this week at the age of 96.

The cult-like figure’s organization — which was once deemed an anti-Semitic political cult by the Anti-Defamation League of B’nai B’rith — confirmed his death on its website Wednesday.

The organization, who described LaRouche as a “philosopher, scientist, poet, statesman,” said he died Tuesday but did not disclose how or where.

“Those who knew and loved Lyndon LaRouche know that humanity has suffered a great loss,” a statement read.

“And today we dedicate ourselves anew to bring to reality the big ideas for which history will honor him.”

Born on Sept. 8, 1922 in Lynn, Massachusetts, LaRouche ran for president for the first time in 1976 as a Labor Party candidate.

He then ran seven times for the Democratic Party nomination in every election until 2004.

He was convicted in 1988 for mail fraud and conspiracy to defraud the IRS by defaulting on over $30 million in loans from campaign supporters,.

But the candidate still ran for president from his 1992 from his prison cell.

Critics said that LaRouche had “fascistic tendencies” and spread lies with his conspiracy theories and predictions of economic doom.

Those conspiracies included a claim that Queen Elizabeth II was a drug trafficker, that former Secretary of State Henry Kissinger and former VP Walter Mondale were soviet agents and that the International Monetary Fund was “engaged in mass murder” by creating and spreading AIDS.

He once called for all AIDS victims to be quarantined, referred to Zionism as “cult nonsense” and said the Holocaust was “mythical.”

He was released from prison in 1994 and in recent years operated from a compound in Leesburg, Va.

His small group of followers are known as LaRouchians.
