During this time in France, Andrea Salaí, another pupil, left Leonardo and built a house on his (Leonardo's) estate in Italy, and so Francesco was the last pupil who continued to work for his master until his death.[16] He was the executor and heir of Leonardo's will.[17] Although Francesco was Leonardo's official heir and was bequeathed with his master's manuscripts, drawings, workshop materials and machinery, Andrea Salaino (Andrea Salaí) received Leonardo's paintings in 1524 in France and brought them back to Milan.[3] Francesco's responsibility attaching him to Leonardo da Vinci was to care for his late master's works after he passed.
