Arthur Cummer, born in Michigan, met Ninah May Holden at the University of Michigan. After studying mechanical engineering for three years, Arthur left the university to enter the family lumber business, which by then had expanded to Florida. The couple married in 1897 and moved to Jacksonville where Arthur worked for the Cummer Lumber Company, later becoming President. He served as director and vice-president of Barnett National Bank, as vice-president of the Jacksonville Chamber of Commerce, and as director of the Children’s Home Society of St Luke’s Hospital. His numerous interests included the National Recreational Association, the Boy Scouts of America, the Evergreen Cemetery Association, and the Home for the Aged of Jacksonville. Privately he collected antique weaponry, bequeathing more than six hundred pieces to the University of Michigan. His wife, Ninah, established The Cummer Museum of Art & Gardens upon her death in 1958. It is important to note that after Arthur passed, Ninah began actively purchasing art for the future museum.
