Percy Edwin Ludgate (2 August 1883 – 16 October 1922) was an Irish amateur scientist who designed the second analytical engine (general-purpose Turing-complete computer) in 1909, following the system of Charles Babbage in 1843. As part of the design, he devised a number of novel techniques, including Irish logarithms.
