'''MAD''' ('''Michigan Algorithm Decoder''') is a [[programming language]] and [[compiler]] for the [[IBM 704]] and later the [[IBM 709]], [[IBM 7090]], [[IBM 7040]], [[UNIVAC 1107]], [[UNIVAC 1108]], [[Philco]] 210-211, and eventually [[IBM System/370]] [[mainframe computer]]s. Developed in 1959 at the [[University of Michigan]] by [[Bernard Galler]], [[Bruce Arden]] and [[Robert M. Graham (computer scientist)|Robert M. Graham]], MAD is a variant of the [[ALGOL]] language. It was widely used to teach programming at colleges and universities during the 1960s and played a minor role in the development of [[Compatible Time-Sharing System]] (CTSS), [[Multics]], and the [[Michigan Terminal System]] computer [[operating system]]s.<ref>{{cite book |last=Alt |first=Franz |year=1967 |title=Advances in Computers |publisher=[[Academic Press]] |pages=143 |isbn=0-12-012104-2}}</ref> The original version of the [[chatbot]] [[ELIZA]] was written in [[SLIP (programming language)|MAD-SLIP]].<ref>{{cite web |last1=Shrager |first1=Jeff |title=Joseph Weizenbaum's Original ELIZA |url=https://sites.google.com/view/elizagen-org/the-original-eliza}}</ref>

The archives at the [[Bentley Historical Library]] of the University of Michigan contain reference materials on the development of MAD and MAD/I, including three linear feet of printouts with hand-written notations and original printed manuals.<ref>[http://quod.lib.umich.edu/cgi/f/findaid/findaid-idx?c=bhlead;cc=bhlead;type=simple;rgn=Entire%20Finding%20Aid;q1=MAD;view=reslist;subview=standard;sort=occur;start=1;size=25;didno=umich-bhl-0351;focusrgn=C01;byte=24555661 Technical Memos], University of Michigan Computing Center publications, 1965-1999</ref><ref>[http://quod.lib.umich.edu/cgi/f/findaid/findaid-idx?c=bhlead;cc=bhlead;type=simple;rgn=Entire%20Finding%20Aid;q1=MAD;view=reslist;subview=standard;sort=occur;start=1;size=25;didno=umich-bhl-0351;focusrgn=C01;byte=24564725 Technical Reports], University of Michigan Computing Center publications, 1965-1999</ref><ref>[http://quod.lib.umich.edu/cgi/f/findaid/findaid-idx?c=bhlead;cc=bhlead;type=simple;rgn=Entire%20Finding%20Aid;q1=MAD;view=reslist;subview=standard;sort=occur;start=1;size=25;didno=umich-bhl-9551;focusrgn=C01;byte=24604876 Topical File 1960-1986], University of Michigan Computing Center records, 1952-1996</ref><ref>[http://quod.lib.umich.edu/cgi/f/findaid/findaid-idx?c=bhlead;cc=bhlead;type=simple;rgn=Entire%20Finding%20Aid;q1=MAD;view=reslist;subview=standard;sort=occur;start=1;size=25;didno=umich-bhl-9551;focusrgn=C01;byte=24695986 MAD (Michigan Algorithm Decoder) 1960-1979], University of Michigan Computing Center records, 1952-1996</ref>
