decided to become a surgeon, he attended a medical school in St. Louis. Grad- 

 uating at the medical school at the age of 21, he continued his studies in Europe. 

 He studied at the University of Leipzig, Germany, from 1857 to i860, then at 



Prague, Bohemia, and at the Uni- 

 versity of Wurzburg, Germany, 

 where the degree of Doctor of 

 Medicine was conferred upon him 

 in 1861. 



He then returned to Mil- 

 waukee, enlisted, and was commis- 

 sioned as second assistant surgeon 

 in the Ninth Wisconsin Volunteer 

 Infantry. In 1862 he was pro- 

 moted, becoming surgeon of the 

 Twenty-fourth Wisconsin Volunteer 

 Infantry. The next four years he 

 spent in active service with his 

 regiment, taking part in many 

 notable battles and campaigns. 



After the war, he entered pri- 

 vate practice in Milwaukee. Later, 

 in search for a milder climate, he 

 practised his profession also in 

 Arkansas and Missouri. In 1885 

 he went with his family to Los 

 Angeles, where he practised until 

 1888, when he accepted appoint- 

 ment as chief surgeon at the newly- 

 founded Soldiers' Home near Santa 

 Monica. He retained this posi- 

 tion seventeen years. 



In 1905 he resigned from his 

 position at the Home, and from all 

 active practice, devoting his time 

 almost wholly to botany, especially to the study of Lichens. 



Dr. Hasse was of a very retiring disposition; he was always a lover of the 

 great out-door world. His Civil War diary shows him already interested in 

 botany, but it was not until 1880 that he began collecting an herbarium. This 

 herbarium he sold later to Columbia University, just prior to his specializing in 

 Lichens. His lichenological studies were made during the last twenty years of his 

 life. His vacations (while surgeon at Soldiers' Home) were invariably spent 

 ^'browsing" in the hills and canyons, or exploring some of the islands near 

 his home, in search of specimehs. His repeated visits to out-of-the-way haunts 

 resulted in establishing a friendship with many a recluse, an isolated fisherman, 

 or a lonely shepherd. On the other hand, it was with the greatest difficulty
