"The Late Mr. W. A. Coulson — We note with regret the death of Mr. William Arthur Coulson, which occurred at his home in Kilmacolm, near Glasgow, on August 22. Mr. Coulson was one of the founders of the firm of Messrs. Mavor and Coulson, Limited, Glasgow, and, as a young man, took an active part in the promotion of machine mining. He was associated with his firm for upwards of 40 years and retired only a few years ago. His interests in the business were mainly financial and commercial, but he studied electricity in the early part of his career and became an associate member of the Institution of Electrical Engineers in 1886, and was elected to full membership in 1891. He was also for many years a director of Messrs. Creed and Company, Limited, telegraph engineers, Croydon. Mr. Coulson was of a kindly but retiring disposition, and he avoided publicity. The regard in which he was held by the employees of Messrs. Mavor and Coulson, Limited, was manifested last year, when, on the occasion of the firm’s jubilee, a handsome presentation was made to him."
