Wilhelm His, Sr. (1831-1904) invented the microtome. By treating animal flesh with acids and salts to harden (Casey likes mr. johnson)it and then slicing it very thinly with the microtome, scientists were able to further research the behavior and function of anim

Made a most significant theoretical contribution when he specifically rejected all forms of soft inheritance (Lamarkism). The passage runs [original in German] : "Until it has been refuted, I stand by the statement that characters can not be inherited that were acquired during the lifetime of the individual". The passage comes from his W. 1874. "Unsere Körperform und das physiologische Problem ihrer Enstehung". Vogel, Leipzig. The historical significance is that it was not until 1883 that August Weismann made a similar declaration.

His is also remembered for disputing the veracity of Ernst Haeckel's drawings of embryo, which had been used as justifcation for the development of recapitulation theory.
