Besides running the first American movie cartoon factory, John Randolph Bray produced educational and industrial films; in fact, Jam Handy, which was a major producer of industrial films, particularly for General Motors' Chevrolet division, began as a branch of Bray's organization.Bray produced travelogues -- or perhaps simply put his name on them and passed them on to the distributors -- into the 1930s, long past the time when he had given up actual production of cartoons. Earlier, he produced a good line of educational films, like this one, which explains how a telephone works through a mixture of live action and animation. It's a good effort and pretty much agrees with what I was taught in class half a century ago when we took a telephone apart.
