Harry Augustus "Hal" Garfield (October 11, 1863 – December 12, 1942) was an American lawyer, academic, and public official.

In 1876 the family moved to what is now the James A. Garfield National Historic Site in Mentor, Ohio, and in 1879 he was sent to St. Paul's School in Concord, New Hampshire.

At the beginning of his final year at St. Paul's he moved to Washington, D.C. to be taught by a private tutor at the White House.

[1][3] At the age of 17 he and his 15-year-old brother James Rudolph Garfield watched in horror as their father was shot down by assassin Charles Guiteau.

[1][4] Garfield taught Roman history and Latin for a year at St. Paul's School after graduating Williams.

In 1908, Garfield became a law professor and eighth president of his alma mater, Williams College in Massachusetts.

Because of the shortage of coal in the northeastern United States, especially in New York City and Ohio, Garfield's administration of the office was severely criticized in the press, but an investigation by the United States Congress showed that the shortage was due to failure of the railroads to meet the extra demands upon them, and federal control of the roads was instituted on December 28, 1917.

This roused a storm of protest from many manufacturers, and the U.S. Senate voted a resolution, requesting postponement, but this reached him after the order had been signed.

He disapproved of the method of settling the coal strike in December 1919 and resigned his office, resuming that of president of Williams College.

After his return in 1935, he moved to Washington, D.C.[3] He was a hereditary companion of the Ohio Commandery of the Military Order of the Loyal Legion of the United States by right of his father's service as a major general in Union Army during the American Civil War.
