...Pittsburgh last week the Westinghouse laboratories announced a new type of lightning recorder. Called a "fulchronograph," it gives a complete picture of a lightning stroke's intensity, from start to finish. Essential feature is a wheel with 400 iron fins on its rim, revolving at 3,400 r.p.m. A lightning arrester no bigger than a quart-size fruit jar receives the bolt, discharges it harmlessly through its coils. In these coils the lightning sets up a varying magnetic field in which the fulchronograph wheel spins. Each iron fin of the fulchronograph is magnetized according to the intensity...
Developed by Engineer Charles Frederick Wagner and his coworkers, the fulchronograph has been tried out on top of the University of Pittsburgh's skyscraper Cathedral of Learning. The record of one bolt passing through the arrester and dissected by the fulchronograph shows that it reached a crest of 21,000 amperes, then fell rapidly (in 100 microseconds) to 1,000 amperes, and from that point more slowly to zero. From start to finish the flash lasted one-sixtieth of a second. Engineer Wagner intends to acquire a complete gallery of different types of bolt, then redesign the arresting equipment...

...Iron and Steel Co. (founded by his father, who was also a co-founder of Standard Oil Co.), looked like Andrew Mellon and had a finger in several Mellon enterprises, few had ever heard of old John Lockhart. He was born, lived and died in the same street in Pittsburgh's east end. He ate sparingly, rarely drank, never married. No intellectual, he read few books, but was fond of the theatre and made a hobby of collecting theatre programs, which he always had autographed by his companions. He was a member of Philadelphia's Union League Club...
Most remarkable fact about John Lockhart was that he gave away most of his fortune (to Pittsburgh hospitals as well as to Rensselaer) anonymously. This month President Hotchkiss wrote to Rensselaer's 11,000 alumni: "It is with sadness that I report his death. . . . Without his gifts the Institute would still be the small school ... of 30 years...
