Portrait of Louis Essen, a senior scientist at Britain's National Physical Laboratory, Teddington, near London, who has worked for 30 years on the measurement of time. He built the first atomic clock using caesium atoms at the Laboratory, and showed that it gives an accuracy equivalent to gaining or losing one second in 300 years., Credit Line: British Information Services, courtesy AIP Emilio Segrè Visual Archives, Physics Today Collection
