1. Lady Margaret Watson-Watt

Margaret Robertson, born in Perth in 1892 , was educated at Perth Academy, and then University College in Dundee where she trained to be a teacher.

In 1916, she married Robert Watson Watt , starting married life as his research assistant at the Air Ministry Meteorological Office. She used her jewellery-making skills to solder connections and make repairs to his apparatus.

During the Great War, Margaret transcribed messages in Morse code, passing them on to British High Command. However, it was her work with Robert that would earn her the moniker, the ‘Mother of Radar’, instrumental as she was in his invention of the early-detection radar that proved vital to the RAF in the Battle of Britain.

The work secured Robert a Knighthood and, in turn, Margaret became Lady Watson-Watt.

In 1942, Margaret filed for divorce from Robert and returned to Perth where she lived until she passed peacefully at the age of 102.
