He graduated from Transylvania University (now Kentucky University) in 1899 with an LL.B. (Bachelor of Laws) degree. One year later, in 1900, he received his M. A. (Master of Arts) degree from Princeton.
Frederick Kershner began a life-long career in education in 1901 as the Dean of Kee Mar College in Hagerston, Maryland, where he remained until 1905. While in Maryland he was also employed as a staff lecturer for the American Society Extension University from 1902 to 1906. In 1906 he moved to Harriman, Tennessee, where he served as the dean of American University.
In February of 1908, the thirty-two year old bachelor was called to become the president of Milligan College. His aging mother, Hannah, came with him, and they quickly made Milligan their new home. One of Kershner's first tasks as president of Milligan was to raise money for a new girls' dormitory, Mee Hall. His fund raising was quite successful. Before he left Milligan not only was the new girl's dorm built and paid for, but over $20,000 had been raised toward the erection of another new campus building. Milligan's enrollment also surged to record highs during Kershner's administration. To President Hopwood's old motto, "Christian education, the hope of the world," Kershner added the more intensive statement, "Character building first of all."
On 25 August 1909, Frederick Married Pearl Katherine Archer of Battle Creek, Michigan. Miss Archer had taught English and German at Milligan since 1904. However, only three years after their marriage, Pearl died of a miscarriage on 13 September 1912. Three years later (on 15 June 1915) he was married to Elsie Martin of Fort Worth, Texas. Frederick and Elsie had three children: Frederick Doyle Kershner, Jr., Mary Eleanor Kershner Trautmann, and Beatrice Pearl Kershner.
In November of 1911 Kershner left Milligan to accept a position as President of Texas Christian University in Fort Worth where he served until 1915. In 1913 while serving at Texas Christian, Bethany College in West Virginia awarded him an LL. D. (Doctor of Laws) degree. Transylvania College awarded him the same degree in 1916. He left Texas Christian University in order to become the editor of the Christian Evangelist from 1915 to 1917 and then a member of the editorial staff of the Christian Standard in 1918-1919. From 1920 to 1924 he served as professor of Christian Doctrine at Drake University. In 1924 he became the Dean of the School of Religion at Butler University and was made Dean Emeritus in 1944. He retired from active service in 1951 after 27 years of teaching there.
Dr. Kershner also served in many other distinguished capacities throughouth the years. He was a member of both the American Society of Church History and the American Theological Society. He was the President of the International Convention of the Disciples of Christ at Columbus, Ohio, in 1938. He is remembered for this thought provoking speech at the convention on "The Imperative of Christian Union. He was the author of several books, including Christian Baptism, 1913; How to Promote Christian Unity, 1916; The Restoration Hand Book, 1918; Sermons for Special Days, 1921; The Christian Union Overture, 1923; Horizons of Immortality, 1926; The Spiritual Message of Great Art, 1928; Pioneers of Christian Thought, 1930; Those Gay Middle Ages, 1939; and Stars, 1940. His first book, The Religion of Christ, 1912, was dedicated to George W. Hardin--A Christian. ----Source: Beside The Waters of the Buffalo: A History of Milligan College to 1941 by Cynthia Ann Cornwell, 1989.
