The 1910 Census shows brothers Fred, 34, and Carl, 31, Bauer as bakers at 702 Broadway in Cape G. Living with them is a third brother, Christian, 24, who is shown as a driver of a bread wagon.
The 1920 Census shows Karl W. Bauer, 42, who has gotten married by this time, and his brother Fred, 43, each shown as "Baker - Own Shop"
Fred Bauer is buried in Fairmount Cemetery and his stone shows 1876 - 23 Apr 1926.
I don't find the Bauer brothers in either the 1900 or 1930 Censuses. I do know there was a movement among bakers nationwide ca. 1902 to move from the 5¢ loaf being standard to the 10¢ loaf. This met with consumer resistance, although I do think there was a difference in size making it less of a "price per slice" increase.
