As of today, 44 men have become president of the United States. Donald Trump is regarded as the 45th president, however, because Grover Cleveland served two nonsuccessive terms.
Only one president of the 44, Gerald Ford, was president without having been elected to the office of either president or vice president, according to the History website. He was appointed to fulfill the term of Vice President Spiro Agnew and then took over as president when Richard Nixon resigned. Eight of the presidents died while in office, four of whom were assassinated. Five presidents have lost the popular vote but won the election in the electoral college. The most recent president in this category is President Donald Trump.
