Thomas Hopley, aged 41 at the time of the incident,
 was a schoolmaster in Eastbourne who ran a private
boarding school from his home at 22 Grand Parade.
 He was well educated and from a middle-class family, the son of a
Royal Navy surgeon and brother of artist
Edward Hopley, author
Catherine C. Hopley, and editor
John Hopley. His household was fairly well off, and he and his wife kept several servants.
 He had two children, the first of which had brain damage – "popular rumour" blamed this on "his unconventionally bracing notions of neonatal care".
 However, Hopley was described by

 He was not a good student, with contemporary sources suggesting he "had

 Hopley attributed Cancellor's failure to learn to stubbornness. On 18 April 1860 he asked the boy's father for permission to use "severe corporal punishment" to obtain compliance,
 with permission granted two days later.
 Hopley did not possess the
cane traditionally used to administer corporal punishment to students, so instead he used a skipping rope and a walking stick.
