Like so many other presidents, Gerald Ford was a lawyer. He graduated from Yale Law School in 1941, in the top third of his class (back when they ranked students). He practiced law in Michigan before entering politics.
Some random trivia. Gerald R. Ford was:
(1) the longest-lived U.S. president ever, exceeding the record set by Ronald Reagan, who also died at 93;
(2) the first person appointed to the vice-presidency pursuant to the 25th Amendment, having replaced the disgraced and scandal-ridden Spiro Agnew; and
(3) the first American president to hold that office without having been elected either president or vice-president, since he assumed the presidency after the resignation of the disgraced and scandal-ridden Richard Nixon.
