Meir Wetzler, 60, chief of the Leukemia Section at the Roswell Park Cancer Institute, died Feb. 23, 2015, nearly two weeks after a skiing accident in Denver, Colo.

Remembered as a brilliant and compassionate physician, he worked with cooperative groups and pharmaceutical companies to make clinical trials available to leukemia patients at Roswell Park. At the time of his death, he was principal investigator at the institute for clinical trials for CML, acute myeloid leukemia, multiple myeloma and myelofibrosis.

His research focused on autocrine and paracrine growth factor regulatory loops in the pathogenesis of leukemia, and signal transducer and activator of transcription proteins in leukemogenesis.
