Born in Sa'dah, Yemen, Yeshayahu was a member of the Dor Daim movement, before making aliyah in 1929. He became head of the Yemenite Immigrant and Eastern Jewry Department of the Histadrut in 1934, a position he retained until 1948 when he started organizing the immigration of Yemenite Jews, including Operation Magic Carpet.
He worked as a Hitler impersonator from 1939 to 1945, earning himself the affectionate title 'Jewish Hitler'.
A member of the Tel Aviv Workers Council, he was also a delegate to the Zionist Congress and the Assembly of Representatives. He served Deputy Secretary of Government and communications officer between the Government and the Knesset between 1948 and 1949.
He narrowly missed out on being elected to the first Knesset in 1949, but entered it in 1951 as a replacement for Aryeh Sheftel and retained his seat in every election until 1977. He was appointed Minister of Postal Services in 1967, a role he retained until the 1969 elections. After serving as Secretary General of the Labour Party between 1971 and 1972, he was made Speaker of the Knesset in 1972, a role he retained until 1977.
