" as a contribution to computer science knowledge. " This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology, " Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell Bull Inc., Groupe Bull " and Bull HN Information Systems Inc. to the development of this operating system. " Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970), " renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership " of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture for " managing computer hardware properly and for executing programs. Many subsequent operating systems " incorporated Multics principles. " Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., " as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. .
