I will never forget that May afternoon in 1970. I was back from Boston, where I was training in pediatric neurosurgery. I had spent a month in John Shillito’s department, who acted as chair after Donald D. Matson passed away in 1969. After Boston, it was obvious that I should continue my training in Chicago with Anthony Raimondi. At that time, the Department of Pediatric Neurosurgery at Children’s Memorial Hospital was one of the most famous in the world since there were few hospitals exclusively dedicated to pediatric neurosurgery. There was Bruce Hendrick’s Unit in the Sick Children Hospital in Toronto, where Harold Hoffman worked, and which was the first in the world to be acknowledged as an independent Department of Neurosurgery. This took place in 1964. I must also mention that Raul Carrea, in 1956, already had a pediatric neurosurgery unit in Buenos Aires. However, actually the first pediatric neurosurgery service in Latin America was established in 1954 by Dr. Miguel Ramos-Murguia at the Children’s Hospital in Mexico City. There was also the Department in Philadelphia with Luis Schut as well as the unit in New York, which was not independent and where Fred Epstein used to practice. In the United States, there were several adult neurosurgeons who were also interested in pediatrics.
