Minister and abolitionist Josiah B. Grinnell founded the city that now bears his name. His home was originally located here, just across from Grinnell's Central Park. Reverend Grinnell assisted enslaved persons by allowing them to stay in his cellar and providing food and supplies. The community soon earned a reputation as home to abolitionists and others who opposed slavery and were willing to assist and defend formerly enslaved persons as they traveled from the South to Canada or other places where they might be in less danger from slave catchers. Grinnell's home was located here until 1914, when part of the home was moved to this location on Broad Street. The home was not well-preserved and the structure was demolished in 1984.
later served in the Iowa Senate and US House of Representatives (where he was
physically assaulted by Congressman Lovell Rosseau for insulting his home state
of Kentucky). He was a benefactor for Grinnell College and later become the
Director of the Rock Island Railroad. Grinnell passed away in 1891 and is
buried at Hazelwood Cemetery in Grinnell.
