The fifteen remarkable individuals in the previous post are all the recipients of the SIGACT Distinguished Service Prize since it was established in 1997. The most striking common feature to all of them is, in my view, that they are all men.
Update: As Lance Fortnow the chair of the selection committee commented below the deadline for this year nomination is April 2, 2017. (Nominations should be sent to Lance to firstname.lastname@example.org and if you need more time nicely ask Lance). Lance wrote that the selection committee welcomes diverse applications.
Here is the description of the prize given in the prize webpage.
The Theory community benefits in many ways from the dedicated service, above and beyond the call of duty, of many of its members. Among other contributions, the field’s members underpin the operation of conferences, journals, prizes, funding agencies, and other community activities, help ensure funding for the field, and promote the recognition of the field by external communities. The SIGACT Distinguished Service Prize is intended to recognize and promote their contributions, as well as to raise awareness of the need for and importance of such service, for the health of our community.
The prize is given annually to an individual who has made substantial service contributions to the Theoretical Computer Science community. (From 2002 to 2012, the award was given biennially.)
