List of Turing Award laureates by university affiliation
This list of Turing Award laureates by university affiliation shows the university affiliations of Turing Award winners since 1966 (as of 2021, 74 winners in total). The Turing Award is awarded every year by the Association for Computing Machinery (ACM) to winners of the previous year, and this list considers Turing Award winners as equal individuals, regardless of the total number of laureates who received the award each time. In this list, universities are presented in descending order starting from those affiliated with most Turing Award winners.
The university affiliations in this list are all official academic affiliations such as degree programs and official academic employment. Non-academic affiliations such as advisory committee and administrative staff are generally excluded. The official academic affiliations fall into three categories: 1) Alumni (graduates and attendees), 2) Long-term academic staff, and 3) Short-term academic staff. Graduates are defined as those who hold Bachelor's, Master's, Doctorate, or equivalent degrees from a university, while attendees are those who formally enrolled in degree programs at a university but did not complete the programs; thus, honorary degrees, summer attendees, exchange students and auditing students are excluded. The category of "Long-term academic staff" consists of tenure/tenure-track and equivalent academic positions, while that of "Short-term academic staff" consists of lecturers (without tenure), postdoctoral researchers, visiting professors/scholars (visitors), and equivalent academic positions. At any university, the specific academic title solely determines the type of affiliation, regardless of the actual time the position was held by a laureate.
Further explanations on "visitors" under "Short-term academic staff" are now presented. 1) All informal or personal visits are excluded from the list; 2) all employment-based visiting positions, which carry teaching/research duties, are included as affiliations in the list; 3) as for award-based visiting positions, to minimize controversy this list takes a conservative view and includes the positions as affiliations only if the awardees were required to assume employment-level duty (teaching/research) or the awardees specifically classified the visiting positions as "appointment" or similar in reliable sources such as their curriculum vitae. In particular, attending meetings and giving public lectures, talks or non-curricular seminars are employment-level duties. Finally, summer visitors are generally excluded from the list unless summer work yielded significant end products such as research publications and components of Turing-winning work, since summer terms are not part of formal academic years; the same rule applies to extension schools of universities.
The number following a person's name is the year he/she received the Turing Award; in particular, a number with asterisk (*) means the person received the award while he/she was working at the institution (including emeritus staff) containing that asterisk. A name underlined implies that this person has been listed for a same institution previously (i.e., multiple affiliations). If a person had multiple positions under one category, only the position with highest rank is considered.
This list, together with the List of Nobel laureates by university affiliation and List of Fields Medal winners by university affiliation, presents the university affiliations of people who have been awarded highest honors in fundamental academic disciplines.
