The succeeding Headmaster was the Reverend Joseph Niblock, writer of "The New Improved Classical Latin and English Dictionary" in 1825. It was praised to the extent that an English-Latin Dictionary was written to translate in the opposite direction. He spent only 11 of his 25 years in teaching at Hitchin, but he helped to improve the School. In one unfortunate incident during his tenure, the son of a Colonel Lousada was killed when he was punched in the nose by William Miller, the grandson of Sir Thomas Miller. The School schedule at that point was a 9 o' clock start and finishing at 12 noon every day except for Wednesday and Friday when the School was closed for public prayer at St Mary's Church. Thursday and Saturday working hours were extended until 3 o' clock in the afternoon as a result. Niblock was also said to be "one of the best Greek scholars in England", and a Greek grammar book that he wrote was in use for many years at Eton College, among other public schools.
