In our new book LOOK INSIDE, dedicated to cutaway infographics, there are only two examples (due to space constrains) of the work of one of the most prolific cutaway artists of all time, and perhaps the first to concentrate most of his efforts in this particular kind of explanation graphics: George Horace Davis. Regrettably, he is almost completely forgotten today, and we feel he deserves to be better known.
G.H. Davis was born in London in 1881. He received a formal art education and was already working as a freelance artist before World War I. He served on the Royal Air Force putting his talent to good use creating aerial diagrams for pilot training. After the war he continued his career as a freelance artist specialized on military subjects, and in 1923 he started his 40-year collaboration with the Illustrated London News. By his own estimate he created more than 2,500 pages of illustrations over a 40-year span, many of them consisting of very detailed technical cutaways of military planes, ships, submarines, and tanks.
Most of his illustrations for ILN are black and white paintings, occupying a full-page or a spread, and sometimes a four-page gatefold. During World War II he created hundreds of paintings revealing the inner workings of about every single plane, ship and tank used by both sides during the conflict.
Besides his work in ILN he collaborated with other British magazines such as Flight and Modern Wonders. In the U.S. Popular Mechanics published his work regularly. He died at age 82 in 1963, and many of his original pieces are preserved in the Imperial War Museum, in London.
There is not a lot of information about Davis online. There are good articles about him here and here. For those interested, It is still possible to find original copies of his illustrations for ILN in Ebay.
