“ Shelley was elected an Associate of the Institution on the 19th May, 1857, and was transferred to the class of Member on the 7th of January, 1879. He was a Fellow of King's College, London, and a Member of the Institution of Mechanical Engineers, to which Society's proceedings he contributed a valuable Paper on "Rope-making."
A gentleman of the strictest integrity and honour, Mr. Shelley was a clever, and, in some respects, a remarkable man; thorough in the accomplishment of everything he undertook, accurate alike in the execution of little things as well as large. ”

“ CHARLES PERCY BYSSHE SHELLEY was born in the year 1827, at Epsom, his father being a physician and surgeon practising in that town.
He received his early education at Dr. Pritchard’s school at Clapham, considered at that period as one of the best private schools in London. From thence he went to King’s College, London, and having early evinced a strong desire to become an engineer, he eventually entered the Applied Sciences Department of the same College under Professor Cowper. ”

“ During the earlier years of his professional career, and before the establishment of Cooper's Hill College, he was particularly successful in the preparation of young men for the Public Works Department of India; whilst later, he had many articled pupils, most of whom are now filling important engineering appointments, either at home or abroad.
Mr. Shelley was for some time associated with the late Sir Joseph Whitworth, Bart. ”
