Thomas Gustave Plant (1859-1941) made his fortune in the shoe manufacturing industry, retiring as a millionaire at age fifty-one, having sold his business to the United Shoe Machinery Company in 1910. Newly married in 1913, Plant then focused on the creation of his New Hampshire country estate. In addition to buying the property known as Ossipee Mountain Park, Plant accumulated land from the Ossipee Mountains all the way to Lake Winnipesaukee, eventually owning 6,300 acres.
