This obituary is part of a series about people who have died in the coronavirus pandemic.

Dr. James T. Goodrich, a pediatric neurosurgeon known for successfully separating conjoined twins in a complicated and rare procedure, died on Monday at Albert Einstein College of Medicine and Montefiore Medical Center in the Bronx. He was 73.

The cause was complications of the coronavirus, according to Montefiore, where he was the director of pediatric neurosurgery and had spent more than 30 years of his career.

Dr. Goodrich was thrust into public view when he conducted a series of four operations over nearly a year on Clarence and Carl Aguirre, twins from the Philippines who were joined at the tops of their heads and shared major veins in their brains. Dr. Goodrich led a team of surgeons at Montefiore’s Children’s Hospital, and the twins’ story generated headlines, including in The New York Times, and was the subject of television specials.

During the final surgery, in August 2004, the team discovered that the twins’ brains were connected by more brain tissue than they had initially thought, a potentially serious complication.
