Schmidt, H. D. (1823-1888).

II. D. Schmidt was born at Marlmrg, Prussia, receiving the usual education of a German boy, then was apprenticed to an instrument-maker at the age of fif- teen, which training in after-life enabled liim to conceive and construct various pieces of apparatus for the benefit of his scientific investigations (his microtome and injector, employed in his researches into the histology of the liver). During his apprenticeship he visited tlie large cities of Europe and came to Philadelphia in 1848, where he began the study of anatomy and constructed jiapier mache models of such correctness and beauty that several are still preserved in the medical department of the University of Pennsylvania. Attracting the attention of Leidy and Jackson, he became pro- sector to Dr. Jackson and assisted Prof. Leidy in many of his physiological inves- tigations. After studying five years, he graduated in medicine in 1858 (Univer- sity of Pennsylvania) and devoted him- self to histology. By his own contriv- ance of an injecting apparatus, he was able to solve the (juestion of the termi- nation of the l>ile ducts of the liver and to demonstrate their origin in the inter- cellular capillaries. In 1860 Dr. Schmidt went south, first to the Medical College of Alabama, in Mobile, and thence to New Orleans, succeeding Penniston as demon- strator of anatomy in the New Orleans School of Medicine. During the Civil War he .served the South as a military surgeon. At the close of the struggle he returned to New Orleans and was installed as pathologist to the Charity Hospital, a position which he occupied for twenty years. He was known as a man of strong convictions, honest and

earnest; never cynical nor prejudiced in regard to the opinions of others. (See article in "New Orleans Medical and Surgical Journal," December, 1888, vol. xvi, n. s.) He contributed to literature:
