In 1978, the members of the Microcirculatory Society, Inc. established The Benjamin W. Zweifach Award ($2,000, a certificate and an engraved gold medal) to be given at the World Congress for Microcirculation. The award recognizes the achievements of internationally renowned individuals whose careers have been noteworthy and who have made outstanding contributions to the advancement of our knowledge of microcirculation.

In the year preceding the World Congress for Microcirculation, members of the Microcirculatory Society and other Microcirculation Societies around the world will be requested to submit nominations for the award to the Chair of the Awards Committee. The nomination packet should include a letter of nomination, letters of support, a Curriculum Vitae and list of Publications. The ten most significant publications during the ten calendar years ending about 18 months preceding the presentation of the award are the principal basis for selection. The awardee will be invited to present a brief summary of his or her research career.

The deadline for the 2023 Zweifach Award is December 15, 2022. Nominations may be sent to Awards Committee Chair, Josh Butcher.
