Hammond was born in Crown Point, New York in November 1884. He came from a family that manufactured iron for generations at Crown Point. His grandfather was Brig. Gen. John Hammond, who served in the Union Army during the Civil War and later became a U.S. Congressman from New York. When the Hammond family's iron works began to suffer as a result of competition from Lake Superioriron ore, the family moved to Chicago. Hammond's father, Charles Lyman Hammond, was a New York native, a graduate of the United States Military Academy, and a real estate businessman. His mother, Mary Electa Hammond, was a Vermont native. At the time of the 1900 United States Census, Hammond lived in Chicago with his parents, four brothers, John, Charles H., Thomas S., and Robert, and two servants. He attended the public schools in Chicago. Hammond's four brothers each became amateur athletes. His older brother, John S. Hammond, was a track and field competitor and football player at the United States Military Academy and was the founder of the New York Rangers. Brother Thomas S. Hammond, also played football for Michigan. The other two brothers were Robert Hammond, who worked for the Whiting Corporation, and architect C. Herrick Hammond.
University of Michigan
Hammond enrolled at the University of Michigan in 1903. He played on the All-Freshman football team in 1903 before joining the varsity team as a sophomore. He played for the Michigan Wolverines football team from 1904 to 1907 and was one of the leading scorers on the 1904 and 1905 "Point-a-Minute" football teams. He played at the halfback, fullback and end positions. The 1906 University of Michigan yearbook noted:
"No better exhibition of pluck was ever shown than his work in the Wisconsin game. Playing without a headgear, he dived headlong int the Badgers' interference time after time, breaking it up and enabling Tom to get the man with the ball. The manner in which he and Garrels outplayed the Chicago ends in the closing game was one of the redeeming feature of that contest. He repeatedly tackled the dreaded Walter Eckersall| Eckersall for losses or forced him to run out of bounds. While not a spectacular player, Hammond's courage and cool make him one of the most valuable players on the 1905 eleven."
Hammond was also a member of the Delta Kappa Epsilon fraternity at Michigan. Hammond graduated from the University of Michigan with a mechanical engineering degree in 1908.
