Heimann Joseph Michael

He showed great acuteness of mind in early childhood, had a phenomenal memory, and was an indefatigable student.

As far as he accomplished this task, it was the foundation of the Ozerot Hayyim, Katalog der Michael'schen Bibliothek, Hamburg, 1848.

Michael took an interest not only in Jewish literature, but in all the intellectual movements of the day, as is shown by the large number of contemporary books and leaflets found in his library.

Rapoport, Luzzatto, Gesenius, Lebrecht, Akiba Eiger, and Leopold Zunz is of great literary interest.

Michael's only independent work was Or ha-Ḥayyim (Frankfort-on-the-Main, 1891), a comprehensive bibliographical and literary-historical dictionary of rabbinical literature, edited by his son, with preface by A. Berliner.
