Roger Lowell Putnam (December 19, 1893 – November 24, 1972) was an American politician and businessman. A member of the prominent Lowell family of Boston, he served as Mayor of Springfield, Massachusetts, from 1937 until 1943, and as director of the Economic Stabilization Administration from 1951 until 1952. During his short tenure in federal office, the nation's steelworkers struck—leading United States President Harry S. Truman to seize the nation's steel mills. For 40 years, Putnam was also the sole trustee of the Lowell Observatory. During that time, he purchased three new telescopes for the observatory and was instrumental in pushing Lowell astronomers to search for Percival Lowell's theoretical "Planet X"—which led to the discovery of Pluto in 1930. Early life and education Roger Lowell Putnam was born on December 19, 1893, in Boston. He was the son of William Lowell Putnam II, a notable and wealthy Boston lawyer.

On his mother's side, Percival Lowell (the noted astronomer) and Abbott Lawrence Lowell (president of Harvard University from 1909 to 1933) were his uncles and the cigar-smoking poet Amy Lowell his aunt.
