In July 1892, several days after graduating from Dartmouth, Hall was hired by the University of Illinois to serve as head football coach and director of physical training at a salary of $1,000. He announced at the time that he would spend the summer working as a waiter at a hotel in Old Orchard Beach, Maine, before reporting to Illinois. He was the third head football coach at Illinois, held that position for the 1892 and 1893 seasons, and led the team to a record of 12–6–4 in his two years as head coach. His 1892 team compiled a 9–4–1 record, played the first games in the football rivalries with Northwestern and Chicago, and played six road games in nine days in late October 1892. Hall was also the first head baseball coach at Illinois, coaching three seasons from 1892 to 1894 and tallying a mark of 30–17. While at Illinois, Hall also studied law at the office of a prominent lawyer in Urbana, Illinois, and organized the first intercollegiate track meet in the Midwest.
Business career
Hall earned an LL.B from Harvard Law School in 1896. He was admitted to the Pennsylvania bar in 1896 and practiced law in Scranton, Pennsylvania. He moved to Boston and was admitted to the Massachusetts bar in 1898. He practiced law in Boston with Samuel L. Powers at the firm of Powers, Hall & Jones. From 1913 to 1917, he was vice president of the New England Telephone and Telegraph Company. In 1917, he became vice president of the Electric Bond and Share Company. He also served as a vice president of the Boston Chamber of Commerce. During World War I, Hall served as business director of the Student Army Training Corps. After the war, he was employed for a time by the War Department. In 1919, Hall moved to New York and became a vice president of the American Telephone and Telegraph Company. In April 1930, he retired at age 60 from his position at AT&T, leaving a reported salary of $50,000. He moved to Hanover, New Hampshire, where he lectured on industrial relations and management at Dartmouth's Tuck School of Business. Even after retiring from his position at AT&T, he continued to serve as a director of several prominent industrial and banking companies and in early 1932 became a director of the United Fruit Company.
Family and later years
Hall married to Sally Drew Hall in 1902. They had three children, sons Edward K. Hall, Jr., and Richard Drew Hall, and a daughter, Dorothy who became Mrs. Laurence G. Leavitt. In 1924, their son, Richard Drew Hall, died after a few hours' illness while a sophomore at Dartmouth. Hall donated an infirmary at Dartmouth that was named Dick Hall's house in honor of his son. Hall died from a heart attack at age 62 at his home in Hanover, New Hampshire, in November 1932. At a funeral service held at the Dartmouth College Chapel, Hall was lauded as "the 'savior' of American college football." He was buried in Dartmouth Cemetery. Famed sports writer Allison Danzig called Hall's death "the heaviest blow football has suffered in years." In 1933, Hall ranked seventh in voting by the Associated Press to select the greatest sports leaders of the past decade. In 1951, he was elected by the country's sports writers and broadcasters as part of the inaugural class to be inducted into the newly organized Football Hall of Fame. Hall's papers were later donated to Dartmouth and are housed at the Rauner Special Collections Library.
