Jewish merchant Samuel Greenblatt, an immigrant from Russia, moved to Fromberg from Gebo in 1900 and built the town’s first commercial building. In 1902 he married Jennie Hetch of Chicago at Temple Emanu-El in Helena. He established a “cash only” mercantile when store credit was the norm and promoted himself as a “square dealing merchant” operating “with justice to all; special favors to none.” His store sold clothing, fabric, furniture, sugar, lard, and other groceries, and he also bought hides, pelts, old rubber, copper, and brass. After moving to Denver in 1909 with Jennie and their two daughters, the family returned to Fromberg in 1911 at the height of the town’s prosperity and built a Colonial Revival home in front of a 1905 two-story wooden barn used to store hay for his horse. Local carpenter W. C. Parker built the modern residence, distinguished by a half-story great room, ornamental woodwork, and a gambrel roof with a tri-foil window in the front gambrel. The mercantile failed in 1913, and the family moved to Billings. Coal company owner W. E. Pinkney bought the home in 1914, then sold it in the 1920s to Martin and Bertha Halpin of Fromberg Pressed Brick and Tile.
