Royal Mathematical School is a branch of Christ's Hospital, founded by Charles II.

It was established so that potential sailors could learn navigation and mathematicians could train at the school.

Samuel Pepys was closely involved in the foundation, in 1673, with Jonas Moore.

[1] The School was integrated into Christ's Hospital, with boys who were pupils being selected aged 11 or 12 and prepared for a career in the Royal Navy.

[3] James Hodgson was master of the Royal Mathematical School from 1709 to 1755, with John Robertson as assistant towards the end of his life.
