Engineering developments 1961

Ever since 1948, Electrical Engineering has published an annual pictorial review of some of the interesting and significant engineering developments of the year. Through the years, it has become increasingly more difficult to keep pace with our exploding technology within the confines of a limited number of pages. As a result, even with the addition of more pages, a relatively small number of significant developments can be covered. This year is no exception. Once again we are indebted to those who answered our request for illustrations. We regret that we could not use all of them. We are especially grateful to Bell Telephone Laboratories for supplying the sketches used as illustrations on some of the following pages.
