Henry Louis Bertrand, known as the Mad Dentist of Wynyard Square, was gaoled in 1866 for 28 years. His crime? The murder of Henry Kinder, husband of Bertrand’s patient and then lover Ellen Kinder. Bertrand was a felon and an amateur artist, as seen in this detailed watercolour of Darlinghurst Gaol which he painted while incarcerated. You can see one of Robert Howard’s many garden beds in the lower left-hand corner. When Bertrand was released in 1894, he went to England, changed his name, and took up dentistry again.
