78 BIOLOGY AND ITS MAKERS 



The portrait (Fig. i8) which forms a frontispiece to his 

 Arcana Naturce represents him at the age cf sixty-three, 

 and shows the pleasing countenance of a firm man in vigor- 

 ous heahh. Richardson says: "In the face peering through 

 the big wig there is the quiet force of Cromwell and the 

 delicate disdain of Spinoza." "It is a mixed racial type, 

 Semitic and Teutonic, a Jewish-Saxon; obstinate and yet 

 imaginative; its very obstinacy a virtue, saving it fromi flying 

 too far wild by its imagination." 



Recent Additions to His Biography. — There was asingular 

 scarcitv of facts in reference to Leeuwenhoek's life until i88;, 

 when Dr. Richardson published in TheAsclepiad * the results 

 of researches made by Mr. A.Wynter Blyth in Leeuwenhoek's 

 native town of Delft. I am indebted to that article for much 

 that follows. 



His Arcana Naturce and other scientific letters contained 

 a complete record of his scientific activity, but "about his 

 parentage, his education, and his manner of making a living 

 there was nothing but conjecture to go upon." The few 

 scraps of personal history were contained in the Elncyclo- 

 pa^dia articles by Carpenter and others, and these were 

 wrong in sustaining the hypothesis that Teeuwenhoek was 

 an optician or manufacturer of lenses for the market. Al- 

 thousrh he sjround lenses for his own use, there was no need 

 on his part of increasing his financial resources by their sale. 

 He held under the court a minor office designated ' Chamber- 

 lain of the Sheriff.' The duties of the ofiice were those of a 

 beadle, and were set forth in his commission, a document 

 still extant. The requirements were light, as was also the 

 salary, which amounted to about ;!(^26 a year. He held this 

 post for thirty-nine years, and the stipend was thereafter 

 continued to him to the end of his life. 



Van Leeuwenhoek was derived from a good Delft family.
