Mac Morgan (June 25, 1917 – June 12, 2007) was an American bass-baritone who had an active performance career in concerts and operas from the early 1940s until the mid-1970s. The Boston Globe described him as a singer "known for his rich tone and enviable diction". After retiring from the stage, he embarked on a second successful career as a voice teacher.
Born in Texarkana, Texas, Morgan moved with his family to Jacksonville, Florida at the age of 9. His father was a lease-inspector for federal buildings. His family attended the Main Street Baptist Church in Jacksonville, and it was there that he had his earliest singing experiences, both as a choir member and soloist. While in middle school he began playing the trombone, and at the age of 16 he began taking voice lessons. After finishing high school in Jackson, he entered the Eastman School of Music in 1936 on the advice of noted baritone John Charles Thomas. He graduated with a Bachelor of Music degree from Eastman in 1940. His voice teacher at Eastman, Arthur Craft, arranged for him to practice with the accompanist Helen Neilly. Neilly and Morgan married in 1941, and remained married until Morgan's death 66 years later. The couple had three daughters together.
After his marriage, Morgan moved with his wife to New York City where he was soon signed with a talent manager. While performing on his first concert tour in 1942, he was drafted into the United States Army . He spent the next 3 1⁄2 years in military service during World War II in the South Pacific and Australia. He spent the majority of his time in the army working in the latter country as a full-time singer; performing in major cities throughout the continent.
After returning to the United States on January 8, 1946, Morgan resided with his family in Darien, Connecticut. In 1946 he began performing regularly on the New York City radio station WQXR with the Paul Lavalle Orchestra. He then was offered his own weekly show by NBC Radio, Highways in Melody, with Lavalle serving as music director and his orchestra accompanying. He commuted into NYC for performances on the show every Friday night at 8:00 at the pay of $130 a week. He also toured with the program for performances in Cleveland, Indianapolis, and Philadelphia among other American cities. In 1948 he performed selections from Jules Massenet's Hérodiade and Victor Herbert's Eileen with soprano Vivian Della Chiesa and Lavalle conducting the New York Philharmonic.
