High School and College

Graduate, Roosevelt High School, Seattle, WA. Mattson sang in the A Capella Choir at Roosevelt High School in 1941-1942. (See Roosevelt High School Yearbook, 1942, p. 93.)

Coursework, University of Washington, Seattle (UW), Seattle, WA, 1946-1947. Glenn Mattson belonged to the Phi Delta Theta Fraternity at the University of Washington. (See University of Washington, Tyee Yearbook, 1946, p. 271.) His projected graduation date changed from 1948 in the 1946 Tyee to 1949 in that of 1947. It is not clear that he graduated, as his name did not appear in the UW Architecture Department Yearbook of 1948-1949 or the Tyeeof 1948, 1949 or 1950.



Born in Denver, CO, Glenn L. Mattson resided with his parents at 6022 30th Avenue NE from at least 1930 until 1951. (See, Source Citation Year: 1930; Census Place: Seattle, King, Washington; Page: 4B; Enumeration District: 0400; FHL microfilm: 2342227, accessed 09/18/2019.) This excluded the time that he served in the US Navy (1943-1945), but included the period that he attended the University of Washington after World War II. (See Seattle, Washington, City Directory, 1948, p. 871 and Seattle, Washington, City Directory, 1951, p. 826.) In 1940, the house had an estimated value of $4360, an average sum for the NE Seattle neighborhood. (See, Source Citation Year: 1940; Census Place: Seattle, King, Washington; Roll: m-t0627-04376; Page: 9B; Enumeration District: 40-73, accessed 09/09/2019.) He seems to have left home after his marriage in 1951.

Between 1953 and 1955, at least, Mattson resided at 4907 236th Avenue SW in what is now Mountlake Terrace, WA, (it was then listed as being in Edmonds), while working for the firm of Warren, Mattson and Bryan, Architects. (See Seattle, Washington, City Directory, 1953, p. 885, Everett, Washington, City Directory, 1953, p. 1140 andSeattle, Washington, City Directory, 1955, p. 908.)

Mattson and his wife, Beverly, lived in Kirkland, WA, in 1957. (See Seattle, Washington, City Directory, 1957, p. 995.) Residing in Kirkland would make sense for a family descended from Finnish immigrants, as a number of Finns clustered in the area. A section of that city is known as "Finn Hill."

Mattson resided on a houseboat at 2235 Fairview Ave East between 1994 and 1998. (See, Source Information U.S. Phone and Address Directories, 1993-2002 [database on-line]. Provo, UT, USA: Operations Inc, 2005, accessed 09/11/2019.)


His mother was Fannie Maria Hooker (born 03/04/1896 in Eureka, CA-d. 09/08/1969 in Kirkland, WA), his father, Erick Julius Mattson, (born 07/30/1888 in Jumala, Finland-d. 04/01/1978 in Seattle, WA). Spellings of his name vary from "Erick" to "Erik" to "Eric." The first spelling was used in documents most frequenlty. Fannie and Erick married on 07/03/1918 in Thermopolis, WY.

Before emigrating to the US, Erik last lived in Mariehamn, the capital of the Åland Islands, in the Gulf of Bothnia, between Stockholm, Sweden and Turku, Finland. He traveled fromSouthampton, England, on about 03/11/1906 aboard the International Navigation Company's S.S. Saint Paul, landing in New York, NY, on 03/18/1906. Mattson made a first declaration of intention to file for naturalization on 06/22/1915 in the US District Court of Seattle.

In 1935, Erik Mattson worked as a carpenter, while Fannie managed the household and worked for Erik's construction company. In 1943, Erik J. Mattson was listed as operating a building construction firm from his residence at 6022 30th Avenue NE. (See Seattle, Washington, City Directory, 1943, p. 748.)

Fannie and Erik had three children: Julius Mattson (born 02/12/1918 in Grable, WY), Edith Mae Mattson Connolly (born 05/27/1920 in Grable, WY-d. 05/20/2013) and Glenn. In 1940, Julius Mattson also worked for his father's contracting business.


He wed Beverly J. Mackenzie on 06/16/1951 in King County, WA. (See, Source Citation Washington State Archives; Olympia, Washington; Reference Number: kingcoarchmc174652, accessed 09/11/2019.)

Biographical Notes

Dates for Glenn L. Mattson's birth vary from 11/26/1924 and 11/26/1925. (The former date was included in Erik J. Mattson's Declaration of Intention for naturalization form dated 04/05/1935. See, Source Citation National Archives and Records Administration (NARA); Washington, D.C.; Naturalization Records of the U.S. District Court for the Western District of Washington, 1890-1957; Microfilm Roll: 27; Microfilm Serial: M1542, accessed 09/11/2019. The latter date was included in Social Security Administration documents. (See, Source Information: U.S., Social Security Applications and Claims Index, 1936-2007 [database on-line]. Provo, UT, USA: Operations, Inc., 2015, accessed 09/18/2019.)

The architect's first name has been spelled variously as "Glenn" and "Glen." The former was the spelling used most frequently. His middle name was recorded as "Laomoin" or "Laomois," and "Lamoine," The former spelling appeared on 1934 naturalization papers for his mother, the last letter difficult to read as either an "n" or a "s." The latter was used in Social Security Administration documents, including the Social Security Death Index. The latter spelling has been selected as being more likely. One other possibility is that these spellings are Anglicized misspellings of a family name "Lehtimaki," a Finnish surname used at one time by Glenn's grandmother, Hilma Lehtimaki (born c. 1874 in Finland-d. 08/04/1941 in Kirkland, WA). "Lehtimäki" is also a parish name in the city of Vaasa, Finland.
