After his military service Capt. Ferguson returned to West Virginia and became a teacher. Ferguson was also a businessman. His biggest venture would be The Ferguson Hotel. Today, The Ferguson would best be described as a business destination. It was a first class hotel which also featured a pool room, barber shop, movie theater, cafe, and convention hall.2 As part of The Block, Charleston's African-American neighborhood, The Ferguson would serve that community for many years.
The Ferguson Hotel was designed by architect John C. Norman, Sr., one of West Virginia's first African-American architects. Norman taught at West Virginia State and designed numerous buildings and remodels of existing buildings throughout the city, including Faulkner Hardware, the garage and showroom for Capitol Motor Sales, Washington Manor, Simmons High School in London WV, and faculty housing at West Virginia State.
