This street originates in the 1872 plat of Terry’s Second Addition to the Town of Seattle, filed by Arthur Armstrong Denny, Henry Leiter Yesler, Erasmus Smithers, and Franklin Matthias, the last two as executors of the estate of Charles Carroll Terry, who was part of the Denny Party of settlers in 1851, and died in 1867. (In 1857, Matthias was listed as being a carpenter, originally from Indiana, Pennsylvania; not too long thereafter, he apparently married and had a child with the daughter of Shilshole Curley [native name Saxkla’xid{?}], “head-man” of the shill-shohl-AHBSH village at šilšul on Salmon Bay. This child, Rebecca Lena Graham, later had to sue Matthias’s relatives to be recognized as his rightful heir. You can read more about her on the Yale University Press blog, at Fitz-Henry Family History, and in the Pacific Northwest Quarterly.)
Today, Alder Street begins at the south entrance to the Harborview Medical Center parking garage, its original first few blocks having been obliterated by Interstate 5, and goes ⅓ of a mile northeast and then east to the Children and Family Justice Center at 12th Avenue.* It resumes at 14th Avenue and goes just over a mile to 32nd Avenue. Finally, just west of 35th Avenue, the Lake Dell Avenue arterial becomes E Alder Street, which snakes ⅕ of a mile down the hill to end at Lake Washington Boulevard. It was originally part of a group of streets named after trees — Pine, Alder, Cedar, and Fir — though Pine and Cedar have since become Terrace and Spruce, since they duplicated street names in other parts of Downtown.
* The Alder Street right-of-way technically begins at Yesler Way just west of 6th Avenue, but is unimproved and indistinguishable from the adjacent open space, and the Interstate 5 right-of-way begins on the east side of 6th.
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.
