Charles Holden [SEP] Early life
During this period he attended draughting classes at the YMCA and considered a career as an engineer in Sir Douglas Fox's practice. In 1891 he began working for his brother-in-law, David Frederick Green, a land surveyor and architect in Bolton. In April 1892 he was articled to Manchester architect Everard W. Leeson and, while training with him, also studied at the Manchester School of Art (1893–94) and Manchester Technical School (1894–96). While working and studying in Manchester, Holden formed friendships with artist Muirhead Bone and his future brother-in-law Francis Dodd. About this time Holden was introduced to the writings of Walt Whitman and became friends with James William Wallace and a number of the members of Bolton's Whitman society known as the "Eagle Street College".
