Radar

Before radar came along the art of stationkeeping in maneuvers and convoys was a very intricate and hazardous problem. In 1937, a 200-mc radar set was tested at sea on USS Leary (DD-158). Two years later, USS New York (BB-34), while she was in a fleet problem in the Carribean at night, tested a greatly improved 200-mc radar set. A group of destroyers (without radar) were attempting a torpedo run on a line of battleships. All ships were in darkness. Aboard New York a group of men in air plot were intently peering at a small flourescent screen when a slightly higher hump appeared in the jagged green line wavering across the screen. They let the "hump" come to 5,000 yards, trained a searchlight in its direction, illuminated, and picked off the oncoming destroyer. Radar had come to life. Upon the Radioman's shoulders fell the brunt of keeping up sound and radar equipment. Operators of this equipment (Soundmen and radar operators, then) were usually Yeomen, Storekeepers, or Seamen, who, if they could distinguish between a "ping" and a "pong" were awarded five extra dollars a month. Communications responsibilities increased and Radiomen couldn't be spared to keep up extra equipment, so in 1943, there were two more ratings established, Radarman and Sonarman.

Thanks for the story Cliff. I love reading stories about radar history and the folks that developed it. I've picked up a small number of books on the subject this year already.

You got any recommended reading? Not just technical, but about the people too.

Cheers!

I found a web page on Naval History. I can't remember where but I'll search and report back (If I can find it that is).

One Person I found that may have been a relative of mine was Lord Kelvin-William Thomas was His last Name.

one of many inventions:
Mirror Galvanometer

Thomson worked with the Atlantic Telegraph Company in the mid-1800s. The Atlantic Cable Expedition of 1857 was an attempt to lay a telegraph cable across the Atlantic Ocean. The expedition was initially unsuccessful but Thomson's mirror galvanometer helped to get the project back on track. According to the National Library of Scotland website, the invention was designed to measure electric current flowing through the newly laid cables, a vital indicator of successful installation. The project was completed in 1866, and the first transatlantic telegraph cable had been laid.

He also Invented the Kelvin Scale
and made a major improvement on the mariners compass.
He worked with His Father at the Glasgow University, Scotland as Professors and had a younger brother that they help go through the university also.
