Lieutenant Colonel Brian Duncan Shaw, MM, TD (10 February 1898 – 7 November 1999) was a British chemistry lecturer at the University of Nottingham,[3] known for his demonstrations on explosives.

After that, he got a bike and spent ten weeks hiding from the Nazis, while trying to reach Spain, eventually cycling 300 miles (480 kilometres).

Near Poitiers, a French gendarme stopped him because the bicycle lacked a plaque used for annual tax, and phoned the Germans, who made him prisoner.

From 1930, he became known for the "Explosives Lecture" which demonstrated a large variety of ways to produce flashes and bangs using chemistry, including the barking dog reaction.

[11][12][13][14][15][16] After his retirement in 1965, he continued giving lectures and worked as an expert witness in several court cases, such as the defence of the Angry Brigade.
