Wilhelm His, Sr. was born on 9 July 1831 in Basel, Switzerland, to Katharina La Roche and Eduard His. He began his medical studies at Basel in 1849 and later transferred to the University of Bern during the winter semester of 1849-1850. A year later, His arrived at the University of Berlin, where he studied under Johannes Müller and Robert Remak. For his clinical training, His attended the University of Würzburg from 1852-1853. During his training, however, His became more interested in the theoretical teachings of Rudolf Virchow, Albert von Kölliker, and Franz von Leydig than in clinical instruction. While at Würzburg, His also studied the writings of Carl Ludwig and Hermann Lotze, and he concluded his schooling with visits to Prague and Vienna, where he met Ernst von Brucke and Karl Rokitansky.

George Linius Streeter was born on 12 January 1873 in Johnstown, New York, to Hannah Green Anthony and George Austin Streeter. He completed his undergraduate studies at Union College in 1895 and received his MD degree from the College of Physicians and Surgeons of Columbia University in 1899. At Columbia, Professor George S. Huntington sparked Streeter's interest in anatomy, and Streeter also interned at Roosevelt Hospital in New York City. He then went on to Albany to teach anatomy at the Albany Medical College and to work with neurologist Henry Hun. In 1902 he studied with Ludwig Edinger at Frankfurt and with Wilhelm His at Leipzig. After working with His, Streeter shifted his focus to embryology, particularly the development of the human nervous system.
