Born in Cavan, Ireland, and came of a medical family, two of his brothers being in the profession. He was educated at University College, London, and Westminster Hospital, and started in practice about the year 1840 in Lyall Place, whence he removed later to Chesham Street. His handsome presence and kindly and courteous manners secured for him a very large practice amongst the upper classes. He was one of the old school of practitioners, and continued to dispense his own medicines to the last. He suffered about the year 1883 from an attack of pneumonia and pleurisy, and retired from active practice. He died at Bath on November 1st, 1887. During his long and tedious illness, which may be said to have lasted from 1883, he was attended by Sir William Jenner. His town practice was latterly at 18 Chesham Street, where his career was most active and almost devoid of holidays. His photograph is in the Fellows' Album. His nephew was William Frederic Teevan (qv).
