Early life

During his years at Uppingham he was introduced to chemistry by his science teacher, a German PhD. After Uppingham he livd at Cotheridge Court. During the 1870s he became an amateur photographer as well as a chemical engineer

, and experimented with the developing processes and photographic materials available to him during that time. Many of his early photographs were scenes taken around the extensive woods and pastures in the vicinity of his family home. By early 1881 he had left Cotheridge

Experiments

During the 1870s photographers used the common wet-plate, which required a lot of on-the-spot preparation for immediate exposure. Although not a new idea, photography

Early death

, probably with the hope that a drier climate would be of benefit to him. He died in Algiers at age 39, unmarried. A plaque in memoriam to him hangs inside St. Leonard's church, Cotheridge, located a short distance from his family home. Herbert Bowyer Berkeley was not fully recognised for his important discovery and contribution to the developing process.
