Reflections Messages Remarks.

The article presents the remarks of former presidents of the Association for Computing Machinery (ACM) on the achievements of the ACM during their tenures. When a president of the ACM comes to the end of his term of office, he passes to another the achievements and the unsolved problems of his administration and the effects of his actions continue to influence the association. According to Walter M. Carlson, president of the ACM from 1970-1972, the ACM has seen a growth among people who were as interested in the use of computing devices as they were in the design and construction of computers. The 1970 census in the U.S. indicates that nearly 300,000 men and women consider themselves professionally engaged in computer-related jobs on a full-time basis. J.H. Curtiss, president of the ACM from 1947-1948, remarked that he hopes the ACM its next 25 years it will continue to maintain its position as the principal channel of dissemination of scientific and technical advancements and of communication in the technological area to which it is dedicated.
