ancestors, the celebrated American writer, poet, and foreign diplomat James Russell Lowell (1819–1891). As Percival Lowell's third cousin, Guy became the sole trustee of the Lowell Observatory after his cousin's death in 1916. Lowell also made a name for himself as a landscape architect. His obituary in The New York Times notes that he designed or "fitted up" gardens for the elder J. Pierpont Morgan, Andrew Carnegie, and the Piping Rock Club. Additional garden-related projects included those of T. Jefferson Coolidge, Mrs. Oscar Lasigi in Stockbridge, Massachusetts, and Payne Whitney in Manhasett on Long Island. Lowell designed many of the gardens and grounds for his numerous residential commissions as an architect, but the most significant project appears to have been the grounds of Harbor Hill (1905); the estate may have been Lowell's largest landscape architecture commission. It is in the area of education that Lowell left his lasting mark on the profession of landscape architecture. He founded the short-lived, but influential, landscape architecture program at MIT (1900–1910). Under his guidance, the program developed as a synthesis of French planning ideals and Italian garden design, with a significant emphasis on horticulture and engineering. The first students graduated from the program in 1902. It was an undergraduate option from 1900 until 1904, and it continued as a graduate course until 1909, with Lowell's offering instruction in landscape architecture until 1912. (He donated his services, asking that his salary be turned over to the Architecture Department.) He taught an important group of landscape architects their trade including Mabel Keyes Babcock (1862–1931), George Elberton Burnap (1885–1938), Marian Cruger Coffin (1876–1957), Martha Brookes Hutcheson (1871–1959), and Rose Standish Nichols. Lowell's program at MIT provided educational opportunities in landscape architecture for women that they could not find elsewhere; many of his female students went on to become outstanding practitioners. Lowell also published several books, including: American Gardens (1902), Smaller Italian Villas and Farmhouses (1916), and More Small Italian Villas and Farmhouses (1920). He also contributed to American Gardens, a photographic magazine. Lowell died suddenly in the Madeira Islands on February 4, 1927.
