To the Editor: Some errors in the article by Max Landsberger of Buffalo entitled "Some Pediatric Milestones of the 19th Century" that appeared in your August 1964 (vol 108:205-210) issue deserve correction, notably in the paragraph on Jacobi on p 207. The passage reads: "Pediatrics as a specialty was introduced to America by Abraham Jacobi, a German clinician of outstanding qualities, who... had to flee his native country in 1848 for political reasons. He became the first professor of diseases of children in the United States, at Columbia University (1860), and he not only founded in the American Pediatric Society in 1888, but also was most influential in raising a new generation of pediatricians in America. He died..., in New York, at the age of 90." I have italicized the incorrect parts. Jacobi graduated at the University of Bonn in 1851 and arrived in New York in or about 1853.
