Our colleague Jacques Kelly has this obituary on Dr. Nicholas J. Fortuin, a popular John Hopkins cardiologist who died today. He was 69.
The physician and professor did research involving new concepts in the distribution of blood flow in heart. During his early years, he developed the first laboratory of echocardiography at Hopkins and promoted the use of this then new technique in a clinical setting.
The cause of death isn't known, but his family says he had been bicycling when he collapsed and died.
