Watson-Watt, Sir Robert Alexander (1892-1973), a British physicist. He developed the first successful radar system, which he demonstrated in 1935. It grew out of a radiolocator device, used to track thunderstorms, that he built shortly after World War I, while assigned to the Royal Meteorological Office's Radio Research Station. Watson-Watt was born in Brechin, Scotland. He was knighted in 1942.
The man who had some theories about relativity was also an eccentric who gleefully eschewed socks, dodged German military service and spurned social conventions.
He built President Eisenhower an indoor golf-training machine, analyzed the Zapruder film and searched for an Egyptian pyramid's treasure chamber using cosmic rays. Aren't you dying to meet this wide-ranging scientist?
