Frederick married Christiane Maria, daughter of Ernst and Amalie Buenger, in Altenburg, Missouri, on January 9, 1866. They had seven children. After her death he married Louise, daughter of Rev. Henry and Mary Louisa Lang and widow of Fletcher Darst, in 1901.
Early adulthood
From Fort Wayne he went to St. Louis, Missouri. to finish his classical education and three years later, in 1865, he was graduated from Concordia Seminary there. He entered the office of the Holy Ministry in the LCMS. Shortly afterward, he suffered sunstroke and had to resign his first call. He re-entered the ministry in 1867 in a small parish which allowed him to regain his strength and study academic subjects. Two years later, in 1869, he entered the Wisconsin Synod's Northwestern College in Watertown, Wisconsin, to continue his interest in classical education. Two years later in 1871 he was called back to the seminary in Fort Wayne to teach.
In Fort Wayne he spent six years in the upheaval that culminated in the Predestination Controversy of 1880. He became a 'persona non grata' due to his outspoken opposition to the leader of the LCMS, C. F. W. Walther. This disagreement led to his being invited to join the Ohio Synod in 1881, and he was called to Columbus, Ohio, to serve as professor of German language in Capital University and professor in the Ohio Synod's Evangelical Lutheran Theological Seminary. He also served as the housefather of the institution, but his term of office as housefather was short. To a man of his academic habits, the petty annoyances that go with that job were distasteful.
His term of office as professor of German was long, and it was not until late in life when natural decline made it necessary for him to have less work that he was relieved. His influence in the German language department made itself felt in the synod because it was largely due to him that the late 19th and early 20th century pastors of the Ohio Synod were known to preach well in German. He taught up until the time of his death while still on faculty at Capital University at age 78.
