MEMOIR OF CHARLES WACHSMUTH 

 BY SAMUEL CALVIN 



Burlington, Iowa, has long been classic ground to the paleontologist, 

 particularly to the student of that special branch of paleontology which 

 deals with the most beautiful of all the fossil forms, the crinoids. Among 

 those who have contributed to bringing the paleontologic treasures of 

 Burlington to the attention of the scientific world we find the illustrious 

 names of Owen, Shumard, Hall, White, Meek and Worthen. When 

 these men had reached the zenith of their fame, Charles Wachsmuth, a 

 man of simple, unobtrusive habit, scarcely known outside a narrow circle 

 of intimate friends, was beginning to study the rare and beautiful forms 

 which the quarries and natural rocky cliffs in the vicinity of Burlington 

 afforded. 



Enfeebled health and the hope of finding relief in out-of-door exercise 

 furnished Mr Wachsmuth the motive for beginning the work of collect- 

 ing crinoids ; but possessing a refined taste and keen appreciation of the 

 beautiful either in nature or in art, it was not long until the exquisite 

 forms which his patience and skill extricated from the rocky matrix con- 

 tributed to the most pleasurable esthetic enjoyment. 



To a mind as gifted as Wachsmuth 's the more purely intellectual ques- 

 tions of morphology, derivation, and natural relationships became in- 

 vested with the keenest interest, and soon the collection and study of 

 crinoids was pursued with an ardor amounting almost to a passion. 

 From Burlington his interest in the subject extended until it compre- 

 hended the crinoids, past and present, of the world. The success of his 

 life-work may be measured by the fact that long before his death Charles 

 Wachsmuth was the acknowledged authority the world over in his spe- 

 cial line of paleontologic investigation.
