A student of
Trinity College, Cambridge, he graduated BA in 1571 and
M.A. in 1575, and was incorporated M.A. at Oxford in 1588. At Trinity College, Hartwell apparently attracted the notice of
John Whitgift, who made him his secretary, reported in this capacity in 1584. A notary public, he was MP for
East Looe in 1586 and
Hindon in 1593. Hartwell is recorded in 1587 as one of the
proctors of the Archbishop of Canterbury's Court of Audience. Hartwell met
Richard Hakluyt, who urged him successfully to translate Odoardo Lopez's account of Africa. Hartwell later wrote that he did so "...to help our English Nation, that they might knowe and understand many things, which are common in other languages, but utterly concealed from this poore Island". He was buried at
Lambeth on 17 December 1606. ==Works==
