The brother of Horace and son of John and Sophia Cadwallader, Herbert was born in Wolverhampton on 24 October 1865. In 1892, he married Amelia Mary W. Keay in Wolverhampton, and by 1901 they were living with their son, Dennis, at 12 Copthorne Road, Wolverhampton. Herbert was working as a manufacturer’s clerk. They were at the same address in 1911 and Herbert was working as a clerk for a fencing works.
Presumably because of his age, Herbert does not appear to have served with the armed forces during the First World War. However, from October 1917 onwards, he did serve the British Red Cross, doing a variety of duties, including hospital work in the military wards of the Wolverhampton General Hospital, transporting the wounded at Wolverhampton and Lichfield, and air raid duty at Merridale Air Raid Station in Wolverhampton. His address by then was given as 207 Tettenhall Road, Wolverhampton. He was awarded a First Aid Certificate.
Herbert died on 16 November 1943. The value of his effects was £1319 9s. 3d.
