Henry Allen Moss (1863-1905)
1906 Obituary 
HENRY ALLAN MOSS, born on the 17th November, 1863, passed through the 3 years’ course at the Royal Indian Engineering College, Coopers Hill, where he distinguished himself in mathematics; and after obtaining his practical training under the late Mr. J. A. B. Williams, Waterworks Engineer of Cardiff, he joined the Public Works Department of Madras in 1886. He was first posted to Bezwada, and subsequently took charge of the Northern Sub-Division, with which the Bezwada district was incorporated. For several years he was engaged chiefly on irrigation work in the Godavari and Kistna deltas, but for nearly 8 years before he left India on furlough at the end of 1903, he was stationed at Madras, where he occupied the post of General Superintendent of the Public Works Department stores and workshops.
The last important work in which Mr. Moss participated was the Cauvery Dam project, in the execution of which he expected to take part on his return to India.
He, however, died in England on the 9th September, 1905, within a fortnight of the date fixed for his departure. Whilst at Madras, Mr. Moss brought out, in conjunction with Colonel A. W. Smart, R.E., their invention of lift shutters or movable weirs, which were introduced on the large anicuts and other regulators of the Cauvery Delta system and subsequently adopted in other parts of India.
Mr. Moss was elected an Associate Member of the Institution on the 4th March, 1890.
