74 HISTORY OF PHYTOPATHOLOGY 



University of Marburg. He served in various positions 

 in the Forest Service. In 1866 he was called to lecture on 

 botany and zoology at the Forest Academy at Ebers- 

 walde, where he remained until 1878, having been made 

 professor of botany in 1871. From Eberswalde he was 

 called in 1878 to the chair of botany in the royal For- 

 estry Experiment Station at Munich, where he remained 

 until his death, October 9, 1901, at the age of sixty-two. 

 The beginning of the Millardetian period found Har- 

 tig already firmly established in his life work. Two of 

 his most classical contributions to our science had al- 

 ready appeared, viz., Wichtige Krankheiten der Wald- 

 baume (1874) and Zersetzungserscheinungen des Holzes 

 der Nadelholzbaume und der Eiche in forstlicher, chem- 

 ischer, und botanischer Richtung (1878). The first 

 edition of his Lehrbuch der Baumkrankheiten appeared 

 the year of Millardet's famous discovery. Hartig 

 appears to have been but little if at all influenced in 

 his work and philosophy by the fungicidal trend and 

 discoveries of the period. An etiologist of the de Bary 

 school, he was little inclined to emphasize control. To 

 the Millardetian period he gave rather than received; 

 a product of the previous period, he became a molder 

 of the etiologic thought of the new. He brought to 

 this phase of our science a biologic and ecologic point 

 of view of great worth and influence. Being a practical 

 forester, he became a field pathologist. In the forest 

 the numerous ecologic factors influencing disease phe- 

 nomena are most in evidence. There he laid out his 

 experiments and there he measured his results. His 

 contributions from 1883 until his death eighteen years 

 later are very numerous and important. He was a
