Even "Every word said in her own praise seemed to be so much taken away from the honour due to her brother. She had lived so many years in companionship with a truly great man, and in the presence of the unfathomable depths of the starry heavens, that praise of herself seemed childish exaggeration." And notwithstanding the honor and recognition which she received from learned men and learned societies for her truly remarkable astronomical labors, her dominant idea was always the same--"I am nothing. I have done nothing. All I am, all I know, I owe to my brother. I am only a tool which he shaped to his use--a well-trained puppy-dog would have done as much." Op. cit., pp. IX, 335 and 346.

[150] Miss Klumpke, the reader may be interested in knowing, belongs to a singularly gifted family. Her sister, Augusta, is a distinguished physician and an authority on nervous diseases. Hers is the glory to be the first woman permitted, after an exceptionally severe examination, to serve as _interne_ in the Paris hospitals. Julia, her youngest sister, who achieved distinction as a violinist with Ysaye, was one of the first to pass the examination required of women entering the Paris _Lycees_, while Anna, the eldest, has won fame as an artist, and as the friend, heiress and executrix of France's famous daughter, Rosa Bonheur. CHAPTER V WOMEN IN PHYSICS Physics, being one of the inductive sciences, received little attention until modern times. True, the Greeks were familiar with some of the fundamental facts of the mechanics of solids and fluids, and had some notions respecting the various physical forces; but their knowledge of what until recently was known as natural philosophy was extremely limited. Aristotle, Pythagoras and Archimedes were among the most successful investigators of their time respecting the laws and properties of matter, and contributed materially to the advancement of knowledge regarding the phenomena of the material universe; but the sum total of their information of what we now know as physics could be embodied in a few pages.
