Marie Walper, the firm’s first associate, single-handedly managed nearly all administrative duties for the company during its formative years. As new personnel came on board later, she remained Mr. Price’s personal assistant and sounding board, helped codify the firm’s corporate ethics and culture, and served as treasurer of the entire corporation.

Isabella Craig initially handled statistical calculations and accounting for the firm for many years, before becoming the secretary of the corporation and a client counselor in charge of many accounts. Early associates credited her elegant, clear speaking and writing style as a major influence on the quality of the firm’s and Mr. Price’s own writings.

Dorothy Krug began her tenure in 1943 when there were only four other associates. The Goucher College alumna handled many duties, primarily secretarial work, accounting, and client counseling. By the time she retired in 1976, T. Rowe Price had grown from a five-person start-up to an internationally known investment management powerhouse.
