CHIEF: Who was the first president to campaign by telephone? Which president personally answered the White House phone? Which president worked as a fashion model?

We thought we knew a lot about the U.S. presidents, but the website Legends of America taught us a thing or two.

William McKinley was the first president to campaign by telephone. The 25th president of the U.S., McKinley was the fifth president from the state of Ohio in a span of 28 years. He was also the first president to ride in an automobile.

Grover Cleveland, the 22nd and 24th president, personally answered the White House phone. He was the only president married in a ceremony at the White House, June 2, 1886, and the first president to have a child born in the White House; his daughter Esther was born in 1895.

While sheriff of Erie County, N.Y., Cleveland was also the public executioner and personally hanged two murderers.

Gerald Ford, the 38th president, once worked as a fashion model for Cosmopolitan and Look magazines in the 1940s. He was born Leslie Lynch King Jr., but changed his name in 1935 to that of his stepfather.

He was the only president whose two assassination attempts against him were made by women.

Ronald Reagan, the first actor elected president, acted in 53 films before becoming president. He was twice named TIME Magazine’s “Man of the Year.”

John Tyler was the president with the most children — he had 15.

John Quincy Adams was the first president to be photographed.

Benjamin Harrison, 23rd president, was the only president to be a grandson of a president (9th President William Henry Harrison) and a great-grandson to a signer of the Declaration of Independence (Benjamin Harrison).

President Benjamin Harrison was the first president to use electricity in the White House. After he got an electrical shock, his family often refused to touch the light switches and sometimes would go to bed with the lights on.
