Not long afterward, in 1912, at "a mere twenty-two years old, he became vice president of ... the Tall Tree Lumber Company", just established in southern Arkansas by William Buchanan in partnership with Charles Lathrop Pack.
Two years later, Randolph returned to Cleveland long enough to marry Georgia Fuller; the newlyweds set up residence in Good Pine, Louisiana.
After a bout with malaria, in 1916 Randolph and his wife returned to Cleveland, where, for the next seven years, he was "vice president in charge of engineering" with the American Multigraph Company, owned by Harry C. Osborne, a friend of his father's.
"[3] Through the Pack Foundation, Randolph "became a founder of the Mexican Institute of Renewable Natural Resources" (Instituto Mexicano de Recursos Naturales Renovables, or IMERNAR), headed by Enrique Beltrán, who received a Guggenheim Fellowship in 1932 for his conservation efforts.
"[6] A further arena of Pack's contributions to international forestry was in helping rebuild the forest resources of Japan and Taiwan, following World War II.
