On this day in 1923 – March 4th – Sir Patrick Moore, English amateur astronomer, writer and broadcaster, was born in Pinner, Middlesex.

He was a prolific author, but was probably best known as the enthusiastic and knowledgeable presenter of the BBC TV program The Sky at Night, which he began in 1957. Although Sir Patrick died in 2012, the program goes on and is the world's longest-running television series.
