HONOURABLE PAUL MARTIN PC CC QC,  Canadian Secretary of State for External Affairs 
Joseph James Guillaume Paul Martin, PC CC QC (June 23, 1903 – September 14, 1992), often referred to as Paul Martin, Sr, was a noted Canadian politician and diplomat.

He completed his university education at the University of Toronto, and earned his law degree from Osgoode Hall Law School. Later, Martin studied at the Graduate Institute of International Studies, Geneva, on a scholarship. 

Martin later opened a law practice in Windsor, Ontario. 

He was first elected to the House of Commons in 1935 and entered the cabinet in 1945. He went on to serve as a noted member of the cabinets of four Prime Ministers: William Lyon Mackenzie King, Louis St. Laurent, Lester B. Pearson and Pierre Trudeau. 

Martin served as Minister of National Health and Welfare from 1946 to 1957 and played an important role in the fight against polio as well as overseeing the creation of hospital insurance in Canada, and is sometimes recognized as a father of Canadian medicare. Martin served as Secretary of State for External Affairs in the Pearson government, and was instrumental in the acquisition of U.S. nuclear weapons for Canadian Forces. 

Prime Minister Trudeau appointed him to the Senate in 1968. He served as Leader of the Government in the Senate until 1974 when he was appointed High Commissioner to the United Kingdom. He also served as Chancellor of Wilfrid Laurier University from 1972–1977, as a result of which the university named the Paul Martin Centre in his honour. Until his death Paul Martin was an Adjunct Professor of Political Science at the University of Windsor. 

His two volume memoirs, A Very Public Life, was published in 1983 (ISBN 0888790929) and 1986 (OCLC 165756245 A very public life: So many worlds Volume 2 of A very public life at Google Books). 
1976 he was made a Companion of the Order of Canada. In recognition of his accomplishments, Martin was granted the right to use the honorific Right Honourable in 1992, a rare honour for one who has never been Prime Minister, Governor-General or Chief Justice of Canada. 

The University of Windsor has a Paul Martin Chair in law and political science, recently held by former Manitoba Premier Howard Pawley (until his retirement from the University of Windsor), and the Paul Martin Law Library. The City of Windsor had also renamed their "Post Office Building" the Paul Martin Sr. Building in his honour on November 18, 1994.
