1899 Obituary 
HOWARD BOWSER died on September 8, 1899, at the age of seventy-five years. He went to Scotland about the year 1847, where he entered into partnership with the late Mr. D. Y. Stewart, the inventor of a method of casting iron pipes vertically. The development of this trade, of which Messrs. Stewart & Bowser are considered the pioneers, has grown to such an extent that it now forms one of the most important of the industries of Glasgow.
Since Mr. Stewart's death in 1882, the capacity of the works, in regard both to quantity and efficiency, has been greatly increased under Mr. Bowser's supervision, and at the time of his death he was maturing a scheme of extensive improvements in the electric power of the works. He was well known among gas and water engineers throughout the world, and was greatly respected.
He was elected a member of the Iron and Steel Institute in 1873.
