Celebrations!

There is a rhythm in the affairs of the Association for Computing Machinery and June marks our annual celebration of award recipients and the biennial election of new officers. I will end my final year as past president, Alex Wolf will begin his first year in that role, and a new president and other officers will take their places in the leadership. June also marks Bobby Schnabel's first appearance at our annual awards event in his role as CEO of ACM. I am especially pleased that two former Stanford colleagues, Martin Hellman and Whitfield Diffie, are receiving the ACM A.M. Turing Award this year. Nearly four decades have passed since their seminal description of what has become known as public key cryptography and in that time the technology has evolved and suffused into much of our online and offline lives.
