This is one of the many streets created as part of the 1895 Seattle Tide Lands plat that were named after U.S. states, including S Dakota Street, Utah Avenue S, and Colorado Avenue S. If I am correct, though, it is by far the shortest, as S Idaho Street begins just east of the Duwamish Waterway and goes just ¼ mile east to E Marginal Way S.
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.
