Dr. Michael Rosenberg, one of those killed in the Maryland plane crash, was well-known in the world of clinical research, but he was also a long-time board member of the Kramden Institute.

Mark Dibner founded the Kramden Institute nearly eight years ago, a nonprofit aimed at bridging the digital divide. He asked Dr. Rosenberg to be on the organization’s board. Dibner had known Rosenberg for nearly two decades at the time and describes him as both a wonderful person and a fantastic researcher.

“From my perspective, the work that he was doing in drug development and what Health Decisions was doing in data collection techniques was just absolutely wonderful,” he says. “It really made a big difference in the field.”

Dibner says he will always remember Dr. Rosenberg’s charitable nature, as he was constantly looking to help those in need.

“He cared about people so much,” Dibner says. “He cared about his employees. He cared about those around him. I wish everybody was like Michael was.”

Dr. Rosenberg was among six killed on Monday when the plane he piloted crashed in Maryland near its intended destination. An investigation into the crash by the National Safety Transportation Board is ongoing.

Rosenberg leaves behind two children, Zachary and Caroline. He was 66.
