[1] Mohr was born in Leuchtenberg in the Kingdom of Bavaria on April 21, 1831, and received a common school education.
In 1859, he married Margaret Zinkel, and as of 1860 they were living with his son John, at that time two years old (Maria may have died in childbirth).
Between 1861 and 1881, they would have nine children of their own: George, Henry, Edward, Theresa, Anna Margareth, Frank, Mary Margaret, Josephine and Michael.
While generally a Democrat,[3] Mohr was elected to the second Manitowoc County Assembly district (the Towns of Cato, Cooperstown, Franklin, Gibson, Kossuth, Manitowoc Rapids and Maple Grove) as a member of the Reform Party, a short-lived coalition of Democrats, reform and Liberal Republicans, and Grangers formed in Wisconsin in 1873, which secured the election of a governor and a number of state legislators.
[6] Mohr, who had been retired for some time, died on May 10, 1907, in Kossuth, having broken his hip in a fall the previous autumn from which he never fully recovered.
