This street was created in 1905 as part of the plat of Southside Garden Tracts, filed by Crawford & Conover, a partnership of Samuel Leroy Crawford (1855–1916) and Charles Tallmadge Conover (1862–1961) (E Conover Court). It appears to have been named after Charles’s son Cecil Tallmadge Conover (1897–1967).
Cecil Avenue S begins at Beacon Avenue S and 37th Avenue S and goes nearly 900 feet southwest to a dead end in the greenbelt above Interstate 5.
Born and raised in Seattle, Benjamin Donguk Lukoff had his interest in local history kindled at the age of six, when his father bought him settler granddaughter Sophie Frye Bass’s Pig-Tail Days in Old Seattle at the gift shop of the Museum of History and Industry. He studied English, Russian, and linguistics at the University of Washington, and went on to earn his master’s in English linguistics from University College London. His book of rephotography, Seattle Then and Now, was published in 2010. An updated version came out in 2015.
