In 1673 he was involved with the establishment of the Royal Mathematical School at Christ's Hospital, which was to train 40 boys annually in navigation, for the benefit of the Royal Navy and the English Merchant Navy. In 1675 he was appointed a Governor of Christ's Hospital and for many years he took a close interest in its affairs. Among his papers are two detailed memoranda on the administration of the school. In 1699, after the successful conclusion of a seven-year campaign to get the master of the Mathematical School replaced by a man who knew more about the sea, he was rewarded for his service as a Governor by being made a Freeman of the City of London. He also served as Master (without ever having been a Freeman or Liveryman) of the Clothworkers' Company (1677-8).
