First dental radiography in America.

Independently of Cary (No. 6122) Rubin performed salpingography. Preliminary communication in Zbl Gynäk., 1914, 38, 658-60.

Bernal and Hodgkin took the first X-ray photograph of a protein structure—crystalline pepsin. They showed that crystals of pepsin give an X-ray diffaction pattern, beginning protein crystallography. This may also be the beginning of structural molecular biology. The paper is freely available from Nature at this link.

Macintyre was the first to demonstrate x-ray cinematography.

Vesiculography first demonstrated.

Astbury, a student of William Lawrence Bragg, was the first to study proteins by X-ray analysis. He applied X-ray analysis to the structure of hair, wool, and related fibers, of which the protein keratin is the principal component, and identified two states: α-keratin and β-keratin. With A. Street. For further information see the entry at HistoryofInformation.com at this link. Astbury's paper is available from jstor at this link.

In 1889 Chauffard gave an important description of pseudoxanthoma elasticum. Further reports on his patient were published by Besnier and Doyon, Darier, and Hallopeau and Laffitte, the last in Ann. Derm. Syph. (Paris), 1903, 4, 595.

“Rowland collected 14 cases of the Hand–Schüller–Christian syndrome, and made the important generalization that it was due to xanthomatosis” (Rolleston).

Excellent pathological study of this condition (“Kaposi’s disease”), which he first described in Virchow’s Handbuch der speziellen Pathologie und Therapie, 1876, 2, 182.
