Abstract

To realize his plans to eliminate individual blastomeres of the ascidian embryo (see Fischer 1992a, b), around 1885 Laurent Chabry devised a sophisticated set of micro-tools for use under the microscope. It is the aim of this essay to describe these tools, to explain his methods of constructing and employing them and to follow their possible influences on subsequent research and on tools developed by later experimental biologists.
