of the morning. Many publications refer to him as an accountant, but that came eight years after his 1909 analytical engine paper. Little is known about his personal life, as his only records are his scientific writings. Until 2016 the best source of information about Ludgate and his significance lie in the work of Professor Brian Randell. As from then, a further investigation is underway at Trinity College, Dublin under the auspices of the John Gabriel Byrne Computer Science Collection. Ludgate died of pneumonia in 19 October 1922, and is buried in Mount Jerome Cemetery in Dublin. Legacy In 1991, a prize for the best final-year project in the Moderatorship in computer science course at Trinity College, Dublin – the Ludgate Prize – was instituted in his honour, and in 2016 the Ludgate Hub e-business incubation centre was opened in Skibbereen, where he was born. In October 2022, a plaque from the National Committee for Commemorative Plaques in Science and Technology was unveiled at Ludgate's home in Drumcondra by the Provost of Trinity College, Linda Doyle.
