Harry Mark Shackelford Sr. was the son of Mark and Mary J. “Molly” Byrd-Shackelford. Born in 1895 in Montgomery County, Indiana, Shackelford lived for a time in New York with his parents before attending Indiana University. At IU, he met his future wife, Lucy, whom he married shortly after graduation in 1917.
They then moved to New York City where Harry worked on Broadway and in radio before beginning a career in sales and merchandizing with the John-Mansville Sales Corporation. He and Lucy gave birth to a son, Harry Jr.
Shackelford retired in 1956 as Vice President after 29 years in which he was instrumental in revolutionizing the development of merchandizing in the building industry.
After his retirement, he and Lucy returned to Indiana. Harry died in Danville, Indiana on August 19, 1982, at the age of 87.
