Meyer studied medicine in Germany in Munich, Berlin and Bonn, where he graduated in 1902, working for three years in the Charite hospital in Berlin before moving in 1905 to work with the eminent pediatrician Heinrich Finkelstein, with whom he also wrote articles and chapters in many medical books.
After Finkelstein's retirement Meyer was appointed director of the Emperor Frederick Berlin Hospital but in May 1933 was forced to resign due to the Nazi racial laws.
In 1935 he immigrated to Israel with his wife Lotte, daughter Ilse and son in law, Professor Walter Hirsch and his grandson Daniel (later psychiatrist and author bestseller Dr. Daniel Offer) and settled first in Jerusalem where he served as head of the Bikur Holim Hospital for a year.
Professor Meyer was the world's leading child nutritionists at his time, studied the salt content of infant nutrition and invented one of the first artificial food for children based on cow's milk.
In 1969, the Municipality of Berlin decided to place a memorial plaque on the site of the department he ran in the thirties in the Kaiser- und Kaiserin-Friedrich-Kinderkrankenhauses Hospital.
