Autobiography of Dr Karl Ernst von Baer

their holdings of multiple copies. A handful of later lists are included, the most substantial from the seventeenth century being that of John Nidd, dated 1659, with a high proportion of medical books. Where the books were bequeathed to College libraries, as Nidd's were to Trinity and Andrew Perne's to Peterhouse, those still to be found on the College shelves have been identified. The owners f...

[Karl Ernst von Baer 1792-1876].

Karl Ernst von Baer (1792-1876) and evolution.

The research program of Karl Ernst von Baer (1792-1876) intended to enhance the comparative approach of animal classification by demonstrating vertebrate affinities (homology). Baer visualized his ideas on development and evolution with an unpublished figure of a branching tree. To buttress his reflections on how species-specific embryogenesis produces a branching tree, he worked out a cladogra...

[Max Ludwig Henning Delbrück (1906-1981)].

Max Ludwig Henning Delbrück applied his knowledge of theoretical physics to biological systems such as bacterial viruses called bacteriophages, or phages, and gene replication during the twentieth century in Germany and the US. Delbrück demonstrated that bacteria undergo random genetic mutations to resist phage infections. Those findings linked bacterial genetics to the genetics of higher organ...
