Differential Analyser

Differential Analyser

Members might like to see my article on my demonstration Differential Analyser, published in the Midlands Meccano Guild magazine, by courtesy of MMG sec Roger Marriott. Richard Hartree’s father, Prof D.R.Hartree built the first Meccano DA in the 1930s. This I understand assisted in the development of gunlaying and bombsight systems and thus helped the war effort. I also attach relevant pages from the June’34 Meccano Magazine. A single stage Hartree DA is in the Science Museum, photo included.  George Sayell WIAS
