ACM at 75

"As its name suggests, the Association for Computing Machinery has been around since the days when computers really were machines that filled entire rooms …".

In January of 1947, the Symposium on Large-Scale Digital Calculating Machinery on the Harvard campus attracted 300 attendees. At that meeting, participants expressed the desire for a professional association that would address the need for communication among those interested in computing machinery. In September of that year, our association was launched with 52 dues-paying members. That number rapidly increased, such that four years later there were 1,113 members, 43 of whom resided outside of the U.S. Today, the ACM is an organization with more than 100,000 members, from 190 countries, serving a community of nearly four million individuals annually.
