Harold (Hal) Abelson is a Professor of Electrical Engineering and Computer Science at MIT, a fellow of the IEEE, and is a founding director of both Creative Commons and the Free Software Foundation.

Abelson holds an A.B. degree from Princeton University and obtained a Ph.D. degree in mathematics from MIT under the tutelage of mathematician Dennis Sullivan. In 1992, Abelson was designated as one of MIT's six inaugural MacVicar Faculty Fellows, in recognition of his significant and sustained contributions to teaching and undergraduate education. Abelson was recipient in 1992 of the Bose Award (MIT's School of Engineering teaching award). Abelson is also the winner of the 1995 Taylor L. Booth Education Award given by IEEE Computer Society, cited for his continued contributions to the pedagogy and teaching of introductory computer science,[2] and the winner of the 2012 ACM SIGCSE Award for Outstanding Contribution to Computer Science Education.[3]

Work [edit]

Abelson has a longstanding interest in using computation as a conceptual framework in teaching. He directed the first implementation of Logo for the Apple II, which made the language widely available on personal computers beginning in 1981; and published a widely selling book on Logo in 1982. His book Turtle Geometry, written with Andrea diSessa in 1981, presented a computational approach to geometry which has been cited as "the first step in a revolutionary change in the entire teaching/learning process."

Together with Gerald Jay Sussman, Abelson developed MIT's introductory computer science subject, Structure and Interpretation of Computer Programs, a subject organized around the notion that a computer language is primarily a formal medium for expressing ideas about methodology, rather than just a way to get a computer to perform operations. This work, through the textbook of the same name, videotapes of their lectures, and the availability on personal computers of the Scheme dialect of Lisp (used in teaching the course), has had a worldwide impact on university computer-science education.

Abelson and Sussman have also been an integral part of the Free Software Movement, including serving on the Board of Directors of the Free Software Foundation,[4] and releasing MIT/GNU Scheme as free software even before the Free Software Foundation existed.

Abelson and Sussman also cooperate in codirecting the MIT Project on Mathematics and Computation, a project of the MIT Computer Science and Artificial Intelligence Laboratory (previously a joint project of the AI Lab and LCS, CSAIL's components). The goal of the project is to create better computational tools for scientists and engineers. But even with powerful numerical computers, exploring complex physical systems still requires substantial human effort and human judgement to prepare simulations and to interpret numerical results. Together with their students, Abelson and Sussman are combining techniques from numerical computing, symbolic algebra, and heuristic programming to develop programs that not only perform massive numerical computations, but that also interpret these computations and "discuss" the results in qualitative terms. Programs such as these could form the basis for intelligent scientific instruments that monitor physical systems based upon high-level behavioral descriptions. More generally, they could lead to a new generation of computational tools that can autonomously explore complex physical systems, and which will play an important part in the future practice of science and engineering. At the same time, these programs incorporate computational formulations of scientific knowledge that can form the foundations of better ways to teach science and engineering.

Abelson is known to have been involved in the publishing of Andrew Huang's Hacking the Xbox and Keith Winstein's seven line Perl DeCSS script (known as qrpff), as well as LAMP, MIT's campus-wide music distribution system. The MIT OpenCourseWare (OCW) project was spearheaded by Hal Abelson and other MIT faculty.

In spring 2008, Abelson initiated the first "Building Mobile Application" class at MIT (6.081). The first class used only the Android platform, and some of the class projects won prizes in the Android Developing Challenge. Future classes also involved other platforms such as Nokia and Windows Mobile. The class emphasizes not only programming, but also presentation skills.

He is a visiting faculty member at Google, where he is part of the "App Inventor for Android" team, an educational program aiming to make it easy for people without programming background to write mobile phone applications and "explore whether this could change the nature of introductory computing".[5] He is the co-author of the book App Inventor with David Wolber, Ellen Spertus, and Liz Looney, published by O'Reilly Media in 2011.

Writings [edit]

Other [edit]

Abelson is also a founding director of Creative Commons and Public Knowledge, and a director of the Center for Democracy and Technology.[citation needed] He's also a Jewish American.[6]

Aaron Swartz investigation [edit]

In January 2013, open access activist Aaron Swartz committed suicide. He had previously been arrested near MIT and was facing up to 35 years imprisonment for the alleged crime of downloading JSTOR articles through MIT's "open access" campus network.[7]

In response, MIT appointed professor Hal Abelson to lead an internal investigation of the school's choices and role in the prosecution of Aaron Swartz by the FBI.[8][9][10]
