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.

Prior to 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 (optional), a list of the nominee's ten most significant publications in the past ten years prior to the WCM, and the nominee's Curriculum Vitae. The ten most significant publications during the ten calendar years 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.
