ZACH, Franz Xaver (1754—1832). Astronomer.

While on the Seeberg, Zach published a series of observations, as well as solar tables and star catalogs. In 1798—1799 he and F. J. Bertuch edited Geographische Ephemeriden, in which the foremost travelers of the period recounted their experiences. This led to the founding of Monatliche Correspondenz zur Beförderung der Erd- und Himmelskunde (1800), in which the latest astronomical news was published. Zach edited this publication until 1813 and later, while in Genova, recommenced it in French, as Correspondance astronomique, géographique, hydrographique et statistique (1818—1826). Toward the end of the eighteenth century he formed an association of twenty-four astronomers, each of whom was assigned a celestial zone to be searched methodically, especially for new comets and planets, a project that culminated in the discovery of the asteroids.

NINETEENTH-CENTURY ALEXANDER, Béla (1857—1916). Radiologist.

In addition to the development of the bone structure the interesting and important research activity Alexander’s covered the X-ray anatomy of the kidneys as well. His reputation was created by the radiographs he called „plastic” or, as they are regarded nowadays, „relief-type”. The plastic pictures invented by Béla Alexander have started the development of X-ray photoengineering, a trend completely neglected so far in X-ray technology.
