MANY science teachers and students will learn with much regret that Mr. A. T. Simmons, inspector of secondary schools for the University of London, and author of a number of widely used text-books of science, died from pneumonia on August 19, at fifty-six years of age. Mr. Simmons received his chief scientific training at the Royal College of Science, London, in 1882-87, and during these years he and his fellow-student, Mr. H. G. Wells, were almost inseparable. After becoming an associate (physics) of the college, he was for three years lecturer in physics, chemistry, and other science subjects at the Southport Science and Art Institute, and while occupying this post he proceeded to work for the B.Sc. degree of the University of London, graduating with first-class honours in physical geography and geology in 1890. During the years 1891-97 he was science and second master at Tettenhall College, near Wolverhampton, where numerous students learned to esteem his high character and teaching aptitude. He came to London in order to undertake general editorial and advisory work for Messrs. Macmillan and Co., Ltd., in connection with school manuals on scientific subjects, and was a part-time member of the staff until his death. I association with Sir Richard Gregory, he founded in 1899 the School World, published by Messrs. Macmillan, and continued as joint-editor when that magazine was incorporated with the Journal of Education in 1918.
