Lloyd Hall was born on June 20, 1894 in Elgin, Illinois. He was an honor student while attending West Side High School in Aurora, Illinois and captained the school debate team while competing in baseball, football and track. Lloyd graduated High School in the top 10 of his class and had to choose between four college scholarship offers. He decided to attend nearby Northwestern University, earning a Bachelor Degree in Pharmaceutical Chemistry in 1916.

While at Northwestern, Hall attended classes with a fellow student named Carroll L. Griffith who would later go on to become the founder of Griffith Laboratories. After graduation, Hall earned a graduate degree from the University of Chicago.

Hall was soon hired by the Western Electric Company through a telephone interview. When he showed up for his first day, however, he was told by a personnel officer that “we don’t take niggers.” Recovering from this slight, he began working for the Chicago Department of Health as a chemist and was promoted in 1917 to senior chemist. The next year he moved to Ottumwa, Iowa where he held the position of chief chemist at the John Morrell Company. During this time, World War I broke out and Hall received an appointment as Chief Inspector of Powder and Explosives for the United States Ordnance Department.

On September 23, 1919 Lloyd married Myrrhene Newsome, a teacher from Macomb, Illinois. Two years later, the couple moved to Chicago where Lloyd began working for the Boyer Chemical Laboratory where he took the position of chief chemist and focused on the emerging field of food chemistry, and began looking at a way of preserving meats with chemicals. In 1922 he moved on to Chemical Products Corporation where he served as President and Chemical director of their consulting laboratory and often consulted with Griffith Laboratories. In 1925, Hall was offered a position with Griffith Laboratories as chief chemist and director of research. Griffith
