Titus van Rijn was born in Amsterdam on September 22, 1641, the fourth child of the famed artist Rembrandt van Rijn and his wife Saskia van Uylenburgh. After Rembrandt's bankruptcy in 1656, Titus and his stepmother, Hendrickje Stoffels, were named in charge of Rembrandt's affairs and began an art-dealership, specializing in Rembrandt's work. At age 15, Titus made a will at his father's insistence, making his father sole heir.
