During his career, Mitch cared for thousands of patients with skill and compassion, amassed a great body of experimental and clinical research, trained and mentored hundreds of physicians and scientists, demonstrated wonderful entrepreneurship, and carved a vision of modern multidisciplinary critical care with lasting benefits for our entire field. For decades, academic medicine has praised the rare individual who excels as the so-called triple threat: teacher, clinician, and scientist. Mitch was all three and more, adding to these triple roles the rare gift of visionary leader in both academia and industry. I have never known anyone quite like Mitch.
