Jesse Barnum Hawley Jr. (March 25, 1887 – March 21, 1946) was an American football coach, inventor, and president of Hawley Products Company. He served as the head coach at the University of Iowa from 1910 to 1915 and at Dartmouth College from 1923 to 1928, compiling a career college football record of 63–28–1. Hawley was the tenth head coach in Iowa football history and led Dartmouth to a national championship in 1925. In 1935, Hawley invented a tropical shaped, pressed fiber sun helmet that was adopted in 1940 by the United States military. Approximately 250,000 of Hawley's military sun helmets were produced during World War II by Hawley Products Company and the International Hat Company. Coaching career Iowa Hawley was hired by the University of Iowa as its tenth head football coach in 1910. Iowa had not won the conference title in a decade, and Hawkeye fans were hoping Hawley could turn Iowa's fortunes around. School officials also hired Nelson A.

Hawley, however, could focus solely on coaching the football team. Hawley's Hawkeyes had a 5–2 record in 1910. The most notable game that season was a loss to Missouri. Before traveling to Columbia for the game, Hawley was warned not to take Archie Alexander, Iowa's talented black tackle, along for the game. Fearing troubles similar to what Frank Holbrook, Iowa's first black football player, encountered in a game against Missouri in 1896, Hawley agreed to leave Alexander behind. When the Iowa team arrived in Columbia, a mob of local townspeople met the team to ensure that Alexander was not with them. In view of the racial incidents as well as the unsportsmanlike treatment Hawkeye players received during the game, Hawley vowed that Iowa would never again play Missouri in football as long as he was the coach. It has been longer than that. The two neighboring state universities did not meet again until the Insight Bowl in 2010. A 1–3 start was cause for concern in 1911, but Iowa finished the year strong and had a solid 4–3 record in 1912. The biggest win of the 1912 season was a 20–7 victory over Iowa State, the last Iowa State team to win a conference title. It was also the final loss in the
