Who was largely responsible for the British application of radar in World War II?

Question

Which ship was sunk in World War II on 17 June 1940 in the course of evacuating British nationals and troops, with the loss of an estimated more than 4,000 men, women and children?

Answer 1

Robert Watson-Watt
Experiments in the late 19th century showed that radio waves were reflected by metallic objects. These and their practical applications were extended over the next 40 years or so. Sir Robert Watson-Watt took these considerably further when he became Superintendent of the new Bawdsey Research Station in the UK in 1936, and developed radar as we know it as a powerful detection tool in World War II. Its applications have widened subsequently to fields including civil aviation, marine navigation, radar guns for police, meteorology and medicine.
