John Bachop Gilfillan (February 11, 1835 – August 19, 1924), known as J.B., was a Minnesota politician and lawyer active in the late 19th century. Gilfillan was born on February 11, 1835, in Caledonia County, Vermont. He attended school at Caledonia County Grammar School, followed by Caledonia County Academy. He began teaching school at age 17. In 1855, he traveled to St. Anthony, Hennepin County, Minnesota to visit his sister, Mrs. John Martin, and decided to stay. His first political position was as a member of the region's first school board. Long a proponent of education, Gilfillan drafted legislation that organized the grade school system in Minneapolis. He was admitted to the bar and began law practice in 1860. Gilfillan served four terms as the municipal attorney for St. Anthony, Minnesota. By 1863, he was the county attorney for Hennepin County. He remained in that position for 10 years, although was briefly replaced by George Robinson (from 1867 to 1869). From 1865 until 1869, Gilfillan was also a city alderman. Before seeking higher office in 1875, Gilfillan practiced law with Lochren, McNair and Gilfillan. Voters placed Gilfillan in his first statewide office in a special election for state senate in 1875. He served as a state senator for 10 years, first representing Minnesota's District 25 and later District 28. He left the senate in 1884 to pursue national office and was elected to the United States Congress to represent Minnesota's 4th congressional district. He served one term but was not re-elected in 1886 when St. Paul mayor Edmund Rice won. He followed that loss with extensive travel to Europe and the Middle East. Gilfillan had been appointed a regent of the University of Minnesota by Minnesota Governor Pillsbury in 1880, and after serving eight years, remained in an advisory capacity. While serving in the Minnesota Senate, he was on the Committee of University Lands and was instrumental in development of the University's Agricultural Experiment Station. Gilfillan endowed the University of Minnesota with $50,000 in 1901 for student scholarships. In 1903, Gilfillan was president of the First National Bank. He continued to work with the bank as a member of its board of directors from 1905 until at least 1907. Gilfillan was married twice. His first marriage was in Vermont to Rebecca Corse Oliphant in 1870. The couple had four surviving children, three sons and one daughter. Rebecca died in 1884.
