When he was twelve, the family moved to Almont, Michigan; helping with the family farm there, Johnson was unable to attend school. When he was sixteen, Johnson sustained a grievous injury and was no longer able to perform manual labor. In 1840, Johnson began teaching school. Three years later, Johnson decided to further pursue his education at Romeo Academy in Romeo, Michigan. In 1846, he was accepted at the University of Michigan in Ann Arbor.
