1920 Obituary 
B. W. WINDER died on July 19, 1920.
After finishing his education in Sheffield he took up the chemical side of the industry, following it with great assiduity at a time when education in this branch was on a very elementary scale. He was regarded as one of the pioneers in the application of chemistry to steel manufacture.
In 1874 he joined the firm of Jonas & Colver, with which he remained connected for the rest of his life. He became works manager, a director of the company, and in 1918 was appointed chairman. A few years ago, in recognition of his work for the Sheffield University, the honorary degree of Master of Metallurgy was conferred upon him, and when the Faculty of Metallurgy was founded he was made a member of it.
He was elected a member of the Iron and Steel Institute in 1903.
