POPULAR PUBUCATIONS 



The Institution published during the year the first of a series of 

 popular publications on scientific and historical subjects related to its 

 important exhibits and collections. Designed for both young and 

 adult readers, the booklet, entitled, "Masters of the Air," depicts in 

 story and pictures the progress of aviation from the first glider flight 

 by the Lilienthal brothers of Germany in the 1890's to the superjet-s of 

 today that fly faster than sound. Included are the stories of the 

 Smithsonian's own former Secretary Samuel P. Langley ; flying planes 

 of the first World War ; the early flights across the ocean and around 

 the world ; and the achievements of the famous "firsts," such as Lind- 

 bergh, Wiley Post, and Sikorsky. The text of the booklet was pre- 

 pared by Prof. Glenn O. Blough of the University of Maryland and 

 formerly science and education specialist of the U. S. Office of Educa- 

 tion, with the technical assistance of Paul E. Garber, head curator of 

 the National Air Museum, and was designed by William D. Crockett, 

 of the staff of the Editorial and Publications Division. The publica- 

 tion was made possible by a grant from the Link Foundation.
