Edward Cyril De Hault Laston

Edward Cyril De Hault Laston (27 April 1883 – 7 November 1951) was a British mnemonist, known for his stage performances and memory recall.

Laston's intention was to join the army, however, a case of rheumatic fever incapacitated him for commission.

In 1907, Laston attended a performance of a popular memory man in a Dublin music hall.

Laston acquired a copy of Haydn's Dictionary of Dates and started committing them to memory.

In the US he did a tour that included dates in New York, Boston, Seattle, and Chicago, as well as Calgary and Edmonton in Canada.
