A portrait of cardiologist Dr. Paul M. Zoll by American artist Joel Babb, capturing the scientist in his laboratory environment.

This portrait by Joel Babb depicts Dr. Paul M. Zoll, a cardiologist known for his contributions to cardiac pacing and defibrillation. Babb, an artist associated with the Contemporary Realism movement, employs a precise, observational approach to capture both the subject and his professional environment. The composition places Dr. Zoll within his laboratory, surrounded by the medical equipment that defined his career. His white lab coat provides a stark contrast to the muted, industrial tones of the surrounding cabinets and electronic devices.

Babb uses a controlled application of paint to render the textures of the laboratory setting, from the metallic surfaces of the instruments to the paper output of the cardiac monitor. The lighting is soft, directed towards the subject to draw attention to his expression and posture. By including the specific tools of Zoll's trade, the artist provides a narrative context that links the individual to his scientific achievements. The work avoids idealisation, opting instead for a grounded, documentary quality that reflects the subject's dedication to his field. The inclusion of the ZolliNTP device, which Zoll helped develop, serves as a specific reference to his medical innovations. This portrait functions as a record of a career spent in clinical research, presented with the technical accuracy characteristic of Babb's practice.
