An architect working in contemporary and modern forms during the 1950s and 1960s in Durham. His firm was called M. A. Ham Associates.
From the 2015 GoTriangle Architectural History Survey for the impact area of the proposed light-rail project, which includes information on the NC Mutual Life building that Ham worked on:
Marion Arthur Ham was born in Florence, South Carolina in 1898, graduated from Clemson in 1918, and began operating his own architectural firm in 1941. In 1955 his office was located in the Snow Building in downtown Durham. In the 1956 directory of the American Institute of Architects he identified his notable commissions as including the Club Boulevard School in Durham (1949), Chowan Hospital in Edenton (1950), and the [C.C.] Spaulding School and Education Building in Durham (1954-1955). The directory notes that he also served as consulting architect for North Carolina Mutual, which would have precipitated his association with Becket a decade later (American Institute of Architects 1955)....Ham was retired by 1970 (American Institute of Architects 1970). He died the following year in Durham. (see p.206 of the report here)
