A familiar and familiarizing run-through of top events in world history- from the campaign of William Jennings Bryan to the Supreme Court decision on segregation- this carries the ring of the Kaltenborn commentaries in picture-story form here. Each phase of the half century of events is recalled as Kaltenborn might have broadcast it, with a personal touch that blends analysis with opinion, making history one man's meat but definitely the cut that will appeal to many. Of Marconi and the wireless, he has to say that the advent of radio made people speech-and-government-conscious and as we read we can hear Mr. Kaltenborn's true observation in our mind's ear. Reporting the Scottsboro case, he gives current opinions about it rather than facts, but these enlighten and enliven too; prohibition and its tragedy he interprets as the intention to rid the country of the less attractive aspects of saloon life, gone wrong to create instead a society of bootleggers and gangsters; the Yalta conference and its failure are attributed to Roosevelt's sickness and to his sincere attempt to make a friend of Russia. And so forth. The commentaries are short, of broadcast length, and, amply illustrated with photographs of the events, they should prove an attractive picture history for the Kaltenborn audience.
