I couldn’t resist snooping around about the history of this property (2110-2112 NE Alberta). Per Oregonian archives and PDX Maps, this business-residential property has had many other uses aside from H.B. Olsen’s watchmaking operation: restaurant & deli (1916), shoe repair shop where one of owners died of stroke on premises (1917-1922), “store” (1924), coppersmith’s shop (1924), barber shop (1925-26), “Alberta Food Lockers” (1948), “Bud’s Plumbing Co. (1956), upholstery shop (1983). The property was for sale and vacant for several longish intervals during 1960-64. It had a 2 BR, 2BA apt. upstairs. In 1920 a local court granted US citizenship to one H.B. Olsen (a Norwegian immigrant) in recognition of his service during WWI.
Jane: Most of that stuff was from the “Oregonian Historical Archive” (Mult. Co. Library web site), i.e., searching on various combos of the address to glean things from the full text of old articles and mostly “business opportunity” classified ads. PDX Maps supplied just a few other details based on permits.
