A number of readers have written in to point out that in our “Postscripts” department for the August/September, 1980, issue, we identified Bruce and William Catton as the authors of The Glory and the Dream . William Manchester, of course, was the author of that book. The Catton book is The Bold and Magnificent Dream . As well, in the “for further reading” note that followed “God Pity a One-Dream Man” in our June/July, 1980, issue, we neglected to mention the fact that The Papers of Robert H. Goddard were co-edited by G. Edward Pendray—himself a pioneer in rocket research and a founder of the American Rocket Society, now the American Institute of Aeronautics and Astronautics. Our apologies to all concerned.
