"......Roberto Busa (November 28, 1913 – August 9, 2011) was an Italian Jesuit priest and one of the pioneers in the usage of computers for linguistic and literary analysis. He was the author of the Index Thomisticus, a complete lemmatization of the works of Saint Thomas Aquinas and of a few related authors.....
.......... In 1946 he graduated in Philosophy at the Papal Gregorian University of Rome with a degree thesis entitled "The Thomistic Terminology of Interiority", which was published in 1949. He was full professor of Ontology, Theodicy and Scientific Methodology and, for some years, a librarian in the "Aloisianum" Faculty of Philosophy of Gallarate.
.......... In 1946 he planned the Index Thomisticus, as a tool for performing text searches within the massive corpus of Aquinas's works. In 1949 he met with Thomas J. Watson, the founder of IBM, and was able to persuade him to sponsor the Index Thomisticus.

Father Busa, the Jesuit priest who invented the hypertext
The pioneer of computer science language has passed away at the age of 98Andrea Tornielli rome If you can read this article, typed using a computer keyboard, it is greatly thanks to him. If PC and notebook have left the typewriter permanently on the sidelines, if we can compose and decompose texts, perform analysis and researches at the click of a mouse, if we increasingly communicate through virtual messages, this is all greatly thanks to him. Father Roberto Busa, a Jesuit, inventor of computer language, forerunner of the active hypertext on the Web fifteen years earlier than American scientists, editor as well of the monumental Index Thomisticus, died of old age on Tuesday evening at the Aloisianum institute in Gallarate. He withdrew here decades ago, where he also found his friend and co-brother Cardinal Carlo Maria Martini. He would have turned 98 this November and until a few weeks ago he was still very active and engaged in new projects.
