Donated by the Jensen Family, 1976; accretions, 1983, 2010.
The Jensen family was one of the first families to settle in the Hayward area of Alameda County (Randall, 1975). In 1860,
Erich Rickert Jensen moved to California, followed by his brother, Jens Christian, in 1864 (The Emigration). Together the
brothers bought 450 acres in the Hayward hills/Eden Canyon area in 1867 (Randall, 1975). In 1871, their mother, Elene, and
the five younger children all moved to California from Fohr because their father, Nahmen, died. Erich traveled back to Föhr
to help the family immigrate to California while Jens Christian stayed in California and completed the ranch for the family
(125 Years). Also in 1871, the brothers completed payment for all 450 acres of land at a price of $7.00 an acre (The Jensen
Family). The ranch house was completed in May
1872 in time for the family’s arrival (125 Years).
The brothers, Erich and Jens, later married sisters and lived together on the Jensen Ranch (Randall, 1975). Jens Christian
married Emilie in 1876, while Erich Rickert married Christiane while in Föhr on the trip to bring his family back to California
(The Jensen Family).
The Jensen Family was active in the local area schools and Jens Christian was a school trustee for many years. In 1892, the
family helped join together districts to form the Union High School District #3 and the first graduation ceremony in 1894
included Newton Jensen, the son of Jens Christian and Emilie (Randall, 1975).
Erwin Jensen, who donated the Jensen Family Papers to California State University, East Bay, is descended from Jens Christian
Scope and Content of Collection
The Jensen Family Papers document the family’s immigration to the United States from Germany and subsequent years in the Hayward
area of California through an extensive body of correspondence written by various family members and spanning from 1750 to
2005. The bulk of the records are dated from the late nineteenth century to the mid-twentieth century. The collection includes
materials in both English and German. Many of the German letters have been translated into English. The correspondence provides
a wealth of information about the experience of immigrating to the United States as well as information about agriculture
and the social life of the family in their new home in California, including birth, death, wedding, baptism, and confirmation
Also included in the collection are watercolor paintings and sketches by family members, part of their book collection, and
