Donaldson Brown (1885-1965) was a financial executive and corporate director with both DuPont and General Motors.
He graduated from Virginia Tech in 1902, did graduate studies in engineering at Cornell University, and joined DuPont in 1909 as an explosives salesman.
In 1912 he came to the attention of DuPont treasurer John J. Raskob, who brought him into the financial activity and encouraged him to use uniform accounting procedures and statistical formulas to evaluate the company's diverse business interests.
In 1918 he assisted in arranging DuPont's purchase of a substantial stake in General Motors from previous chairman William C. Durant, and later that year became treasurer of DuPont replacing Raskob. In 1921 he became treasurer of GM to help protect DuPont's investment in the struggling auto maker, and in 1924 he was appointed to the executive board of GM. His introduction of standard financial ratios (return on investment and return on equity) and flexible budgeting allowed the company to effectively manage their decentralized empire. During this time he worked closely with legendary GM head Alfred P. Sloan.
Brown retired as an active executive with GM in 1946, but remained on the board until 1959 when he and 3 other directors had to resign due to interlocking directorships with DuPont.
