The name of the street comes from the "Free School" which was established in the 17th century by Dr Stephen Perse who left money in his will to educate 100 boys from Cambridge, Barnwell, Chesterton and Trumpington. This school later became the first site of the Perse School (now in Hills Road). The Whipple Museum is situated in the original school hall.
