In 1935, Henry Ford Macomb Hospital opened the area's first pediatrics department and six years later began preparing its nurses for war. In 1943, the hospital's School of Nursing became a member of the United States Cadet Nurse Corps. During this same period, Henry Ford Macomb broke racial barriers and admitted the county's first African-American physician to its medical staff. Dr. Lewis Rickman recalls a historic first: "It was around 5:30 in the morning July 4, 1949, and I had just started. I delivered the first African-American baby born in a Macomb County hospital that day. Now that's a first to be proud of!"
