Did Sojourner Truth attend a college?

No, she did not. In fairness, Sojourner Truth (real name Isabella Baumfree) was alive in the early to mid-1800s, a time when few woman, black or white, attended college. In fact, only the wealthiest, elite white Christian men had the opportunity for higher education. Sojourner Truth would have been taught privately, or she would have apprenticed and learned by doing, which is how most people of that era were educated.
