SLOTTED WAVE GUIDE RADAR EXHIBIT

One of the island’s most accomplished high school graduates was Dr. Ernest Guptill, who was working on his McGill University PhD thesis when he became the co-inventor of the slotted wave guide for radar.  Dr. Guptill grew up on the island and later became the Head of the Physics Department at Dalhousie University.  The story of his wartime invention during WWII is little known, but it is credited with helping to win the Battle of Britain and WWII for the Allies (his radar invention revolutionized air surveillance and safety).  It also helped make smaller and more efficient radar on fishing boats a reality and that made marine navigation safer for everyone.

 

On display:  Read about his life, his discovery and his tragic accidental death.  On display is a radar common on fishing boats in the 1970s that you can activate by pushing a red button on the wall.
