INTEODUCTION XIX 



while laboring in a common cause. The professor and 

 the social apostle dominated in him. Pasteur was 

 especially a discoverer. Original, profound and slow, 

 he was made to walk alone. He said "we must seek." 

 His disciple added "we must organize and convince." 

 Roux understood both points of view, went from one to 

 the other, and effected a reconciliation, for each one 

 maintained his own ideas only in the interest of the 

 foundation. And so the years passed on, each year 

 giving more and more into Duclaux's shaping hand, until 

 the Institute became such as we see it to-day. 



"To this great foundation Pasteur bequeathed a sci- 

 entific tradition but it was Duclaux who created its soul" 

 (Bloch).i 



One of Duclaux's first efforts, begun even before the 

 Institute was opened, was the founding of a journal 

 which should be a worthy exponent of the new ideas. 

 Thus came into being in 1887 ^^Les Annales cle VInstitut 

 Pasteur,^' which has done so much for the advancement 

 of human and comparative pathology, and to which 

 Duclaux devoted all of his energy and ability. In this 

 journal, the first volume of which was organized around 

 the doctrine of immunity, he realized an old dream of 

 Raulin, his comrade of other days. 



In many ways Duclaux's interests deepened and diver- 

 sified in these years. In 1888 he became a member of 

 the Academy of Sciences, in the section of rural economy. 

 In 1890 he entered the National Society of Agriculture. 

 In 1894 he was elected a free member of the Academy of 

 Medicine. And always there were his Annales. 



"My journal (1892) gives me twice as much work since it threatens 

 to become twice as large as at the beginning. I have two laboratories 

 to conduct with two categories of students. In short I am driven: 

 rus quando tc aspiciam! "
