Meridor was born in Poland in 1913, as Yaakov Viniarsky, to a family of middle-class merchants. After hearing reports of the first Arab rebellion in Mandatory Palestine, he became a member of the Betar Movement in 1930. He studied law at the University of Warsaw.
He immigrated to Palestine in 1932, and joined the Irgun a year later. In 1941 he accompanied David Raziel on a mission to Iraq in order to sabotage oil fields on the outskirts of Baghdad. When Raziel was killed along with a British officer, Meridor returned to Palestine and took over as Chief Commander of the Irgun.
In 1943, Meridor relinquished command of the Irgun to Menachem Begin, but held senior positions in the Irgun until the Haganah handed him over to the British in 1945. He was sent to various detention camps in Africa, and carried out daring escape attempts, finally succeeding in 1948 and arriving in Israel on the day independence was declared.
According to The Scotsman, the Irgun announced in Tel Aviv on 7 April 1948 that 'Jacob Meridor' had "taken over his war assignment" in Palestine. The Scotsman also reported that Meridor's first command was the raid on Pardes Hana military camp, South of Haifa, in which 6 British soldiers and their commanding officer, Lieut-Colonel G.L. Hilderbrand, were killed.
Under Begin he was charged with the task of managing the Irgun's integration in the newly formed Israeli Defense Forces.
In the political sphere Meridor was one of the founders of Herut and was elected to the Knesset in Israel's first elections. He retained his seat in elections in 1951, 1955, 1959, 1961 and again in 1965 after Herut had merged with the Liberal Party to form Gahal (which later became Likud). He also published a book in 1955, entitled Long is the Path to Freedom: Chronicles of one of the Exiles. However, he lost his seat in the 1969 elections.
Meridor resurrected his political career in 1981 when he was elected to the Knesset on Likud's list. Despite his pre-election embarrassment at falling prey to the Bulb to light all Ramat Gan hoax, he was appointed Minister of Economics and Inter-Ministry Coordination by Prime Minister Begin. He retained his ministerial position when Yitzhak Shamir took over from Begin in 1983.
Despite his high rank within the government, Meridor lost his seat again in the 1984 elections, and did not return to the Knesset.
