The house at 1018 N 7th Street was built circa 1892 for Richard and Hattie Wells in the Colonial Revival style with an American Foursquare form. The approximate cost of construction was $5,000. Richard and Hattie owned the house until 1898, when it was sold by the sheriff on their behalf to C. B. Cauldwell for $4,499. Given contemporaneous newspaper coverage of the couple, it's likely that the house was sold at auction after they defaulted on their mortgage.
By 1899, the house was owned by Otto and Paula Richter. Otto Richter was born in Remscheid, Germany in 1856 and received a degree in mechanical engineering from the University of Berlin in 1878. He immigrated to the United States in 1879, settling first in Hokendauqua, Pennsylvania, where he worked as a machinist and then as a factory foreman. In 1892, Richter made his way to the Pacific Northwest, joining his brother Franz in his Seattle rubber business, the Washington Rubber Company. The company eventually opened branch offices in Tacoma, Portland, San Francisco and Spokane.
Otto married Paula Ehrenberg in 1896, and they had two children - Ella and Ottilie. In 1904, Otto accepted the office of acting consul for Germany, and he was later appointed vice consul. Otto died in 1941, and Paula in 1943.
Nathan and Ellen Blakeslee lived in the house between 1949 and 1975, operating a nursery school and kindergarten on site. The Blakeslee School is thought to have been one of the first preschools in the city.
As a contributing structure in Tacoma's North Slope Historic District, the Wells-Richter House is listed on the local and national registers of historic places, with the possibility of a significant property tax abatement.
