Dr. Karl Neumann (1931-2021) was a pediatrician in Forest Hills for over 50 years. Throughout career in pediatrics and travel medicine, he provided his patients, their parents, students, and readers of his blog with the most thorough advice and information available on keeping children safe and healthy in a friendly, humorous way. He immigrated to the United States in 1941, after a two-year stay with a foster family in Sweden and an arduous trip across Siberia (on the Kinder-transport.) He received his medical degree from State University of New York Downstate College of Medicine, did his internship at SUNY Downstate Health Sciences University and residency in pediatrics at New York Presbyterian Hospital. He was an academician and teacher, serving as Clinical Associate Professor of Pediatrics at Weill Medical Center of Cornell University and Clinical Associate Attending Pediatrician at New York Presbyterian Hospital/Cornell Medical Center. 

In 1974, he began to integrate travel medicine into his practice, as the Travel Health Center, offering advice and vaccinations to patients, and pursuing travel writing. He lectured widely to students and peers in areas of travel medicine, wilderness medicine, and pediatrics, and was widely acknowledged as one of the leading specialists in the world in the interface of pediatrics and the wilderness. He was editor of Wilderness Medicine Magazine, the International Society of Travel Medicine's newsletter, and the International Child Health newsletter published by the American Academy of Pediatrics, and has written chapters on pediatric travel medicine in medical textbooks and the author of many articles in major newspapers and magazines. 

The International Society of Travel Medicine awarded Dr. Neumann its Lifetime Achievement Award, as the society's "soul and conscience", highlighting how he facilitated transparency and communication and played a leadership role in pediatric travel medicine issues. In his own popular blog at kidstraveldoc.com, he specialized in preparing parents for trips abroad with vaccinations and advice on traveling with kids, especially those going to exotic places or with chronic diseases, like diabetes, which could be affected by being away from home.
