Lincoln Ware Riddle was born on October 17, 1880 in Jamaica Plain, Massachusetts, to Charles Wisner and Mary Brastow Riddle (née Ware). He became interested in botany while attending Roxbury Latin School. Riddle graduated from Harvard in 1902, going on to earn A.M. and Ph.D. degrees from Harvard in 1904 and 1906.

In June 1906, Riddle married Gertrude Hollister Paine. That fall he was appointed instructor in botany at Wellesley College, filling in for Clara E. Cummings while she was on leave. After her death the following spring Riddle remained at Wellesley, taking over management of her lichen herbarium and eventually becoming full professor in 1917.

Riddle was appointed assistant professor of cryptogamic botany at Harvard in 1919, a position he held only one year before becoming ill. Riddle died on January 16, 1921, in Cambridge. Gertrude died in 1976.
