• Marking the 50th anniversary of the death of Winston Churchill, a new exhibition at the Science Museum in South Kensington looks at his passion for science and the influence that had on bringing World War II to an end. Churchill’s Scientists celebrates the individuals who flourished under Churchill’s patronage (and , as well as helping to bring about the end of World War II, also launched a post-war “science renaissance”) – from Robert Watson-Watt (inventor of radar) through to Bernard Lovell (creator of the world’s largest telescope) – and also delves into more personal stories of Churchill’s own fascination with science and tech. The display include objects from the museum’s collection as well as original archive film footage, letters and photographs. Highlights include the high speed camera built at Aldermaston to film the first microseconds of the detonation of the UK’s first home grown atomic bomb, the cigar Churchill was smoking when he heard news of his re-election as PM in 1951, and a one-piece green velvet “siren suit” designed by Churchill to wear during air raids (only one of three originals known to exist, it’s never been on public display outside of the tailors who created it). The free exhibition runs until 1st March and is part of the Churchill 2015 programme of events. Visit www.sciencemuseum.org.uk/churchill for more.
