In April 1907, a Society for Christian Instruction was formed to explore the possibility of founding a school in the neighborhood known as the "Groninger Hoek.

"[14] After a year of growth, the society chose the name "Timothy" for their proposed school to honor the New Testament evangelist who had been raised in a Christian home and given spiritual instruction by the apostle Paul.

[17] Early in 1927, Timothy was able to sell its Tripp Avenue school building to a Jewish congregation, but were forced to vacate within six months.

[18] It was decided to build the new school in Cicero, Illinois because it was a central location to many of the families that had relocated west of the city of Chicago.

In 1965, a group of African American parents attending Lawndale and Garfield Christian Reformed Churches asked the Timothy board permission to enroll their children at the school.

[20] Cicero was, at the time, a town with around 70,000 residents of European descent and had earned the reputation as the “Selma of the North.”[17] One black family had attempted to move into the city in 1951 and they had been chased out by a white mob.
