Petrus Dasypodius in the context of "ISBN (identifier)"

Josua Maaler (also Maler, Mahler, Latinized Pictorius; 1529–1599)was a Swiss pastor and lexicographer. He was the author of the first dictionary which focused exclusively on the German language, published in Zürich as Die Teütsch Spraach in 1561.

Maaler followed the Dictionarium Latinogermanicum by Petrus Dasypodius (1536) in giving the German lemmas alphabetically, as opposed to the earlier Dictionarium Latino-Germanicum by Johannes Fries, which gave German glosses on Latin lemmas.

Conrad Dasypodius (1532 – 26 April 1600) was a Swiss astronomer, mathematician, and writer. He was a professor of mathematics in Strasbourg, Alsace. He was born in Frauenfeld, Thurgau, Switzerland. His first name was also rendered as Konrad or Conradus or Cunradus, and his last name has been alternatively stated as Rauchfuss, Rauchfuß, and Hasenfratz. He was the son of Petrus Dasypodius (Peter Hasenfuss) (1490–1559, or Peter Hasenfratz), a humanist and lexicographer.

In 1564, Dasypodius edited various parts of the Elements of Euclid. In the preface, he says that for 26 years it had been the rule at his school that all who were promoted from the classes to public lectures should learn Book I of the Elements, but there were no longer any copies to be had so he was bringing out a new edition so as to maintain a good and fruitful regulation of his school.
