Franz Ignaz Cassian Hallaschka and his book “Elementa Eclipsium”. (English) Zbl 0959.01024

On occasion of the total solar eclipse of August 1999, the author tells in \(2{1\over 2}\) pages about the life of the Moravian astronomer Hallaschka (1780-1847) and in particular about his Elementa eclipsium from 1816, which contained calculations of solar eclipses for the years 1816-1860 (with an atlas of eclipses going until 1910) and whose method to some extent anticipated that of Bessel. Two notes of slightly less than a page each list a selection of Hallaschka’s publications and the instruments of his observatory. Many diagrams from the Elementa are reproduced. No sources are given for the biographical information.
