Born in Bristol in 1869 and was educated at Taunton Grammar School. After being in business for some years, he turned to medicine on coming of age and studied at University College, Bristol, where he won prizes in anatomy, and at the Bristol General Hospital he was Martyn Memorial Pathological Scholar and Medallist, later Surgical Casualty Officer. He also studied at St Bartholomew's Hospital. After acting as House Surgeon to the Bristol Hospital for Sick Children and as Resident Medical Officer to the Sunderland Royal Infirmary, he started in practice at Nottingham in 1897. He was appointed Surgeon to the Children's Hospital, and in 1901 Assistant Surgeon to the Nottingham General Hospital, later becoming Surgeon. He restricted his practice to surgery, and during the War (1914-1918) undertook various duties in the Military Hospital of the Nottingham Area. From being apparently in good health, he was struck down by illness and died on June 26th, 1918. He had practised latterly at 7 Regent Street, Nottingham, and was survived by his widow and two daughters. Willis was a brilliant surgeon, a skilful diagnostician, and a most agreeable, kindly, and courteous colleague, always ready to give help and advice in difficult cases, and eager to assist the younger men in any way he could.
