Mortimer M. Bortin, M.D., was one of the founding members of the IBMTR and served as its Scientific Director for more than 30 years. The Mortimer M. Bortin Award, established to commemorate Dr. Bortin's contribution to the field of transplantation, is presented each year to one or more investigators submitting abstracts for presentation at the annual IBMTR/ABMTR meeting. The abstracts must address important issues in experimental or clinical blood and marrow transplantation and be deemed to be of outstanding scientific merit. This year, three $1,000 awards will be presented on behalf of the Mortimer M. Bortin Fund Awards Committee. The awards are supported by an educational grant from Gambro BCT, Inc.
