US Presidents are elected by the Electoral College. However, there were six Presidents who served in office without being endorsed by popular vote. Gerald Ford was one of them; he became president after Richard Nixon resigned in 1974, and was not elected at the end of the term. The other part of the question is a trick. George Washington was never elected by popular vote, but he was elected by the Electoral College (like all Presidents) in 1789 and 1792.
In his election as President, Andrew Jackson had more popular votes and more electoral votes, but John Quincy Adams was elected by the House of Representatives because no one had a majority. President Adams was the first President to be elected without receiving a majority of the popular or electoral votes. President John Quincy Adams was the first President to wear trousers at his inauguration. In 1826, the Marquis de Lafayette gave John Quincy Adams an alligator.
