...this unfamiliar phenomenon electrical engineers took little note until three years ago when Karl Boyer McEachron, General Electric Co.'s ace lightning researcher, started a study of bolts which strike Manhattan's 1,230-foot Empire State Building, a giant lightning rod. During his study Mr. McEachron observed that several strokes which hit the skyscraper made no noise. Last week he had an explanation...

Because the Empire State Building is struck so frequently, researchers of General Electric Co., looking for light on lightning (to help them protect transmission lines) began to photograph it from another building. The research was under the direction of Karl Boyer McEachron, 48, G. E.'s ace lightning researcher, who has been designing experimental apparatus Pittsfield for 16 years, has produced artificial bolts of 10,000,000 volts, others of 250,000 amperes (amperage is the amount of current, voltage the pressure which drives it). Last week Engineer McEachron reported the results of three summers of Empire State Building...

...necessary before the ground is reached, but the whole descent occurs in 1/100 sec. or less. When the stepped leader reaches the ground, the main stroke, more powerful than the leader, shoots upward to the cloud along the path created by the downward steps. In general the McEachron crew confirmed Schonland's findings, but they discovered that in some instances the leader stroke did not shoot downward from the cloud but upward from the building's top. They got pictures of branched lightning which forked upward...

...Pittsfield have been puttering with artificial lightning for 20 years. They have produced 10,000,000 volts (at comparatively low amperage) in a single discharge. Karl Boyer McEachron, 44, designer of the high-amperage apparatus which he demonstrated last week, has been at Pittsfield for twelve years. His spectacular experiments are useful for testing purposes, for studying the destructive effects of natural lightning and means of combating them. When he is not in the laboratory he troops up & down the country lecturing on lightning...

...protecting rural homes and buildings, Mr. McEachron declares a good lightning rod is effective 99 times in 100. In use since Benjamin Franklin's time, lightning rods and the glib agents who sold them were long in disfavor with farmers because so many rod-equipped structures were struck by bolts and burned. But this was found due in almost every case to faulty installation. Nine-tenths of the deaths caused by lightning in the U. S. (some 50 per year) occur in the country. Cities are much safer because big buildings, with steel frames acting as lightning rods...
