“ Zachariae's true history is in his writings, which are extremely numerous and multifarious. They deal with almost every branch of jurisprudence; they are philosophical, historical and practical, and relate to Roman, Canon, German, French and English law. ”

“ His son, Karl Eduard Zachariae (1812-1894) , also an eminent jurist, was born on the 24th of December 1812, and studied philosophy, history, mathematics and languages, as well as jurisprudence, at Leipzig, Berlin and Heidelberg. Having made Roman and Byzantine law his special study, he visited Paris in 1832 to examine Byzantine MSS., went in 1834 to St Petersburg and Copenhagen for the same purpose, and in 1835 worked in the libraries of Brussels, London, Oxford, Dublin, Edinburgh and Cambridge. ”

“ The first book of much consequence which he published was Die Einheit des Staats and der Kirche mit Rücksicht auf die Deutsche Reichsverfassung (1797) , a work on the relations of church and state, with special reference to the constitution of the empire, which displayed the writer's power of analysis and his skill in making a complicated set of facts appear to be deductions from a few principles. ”
