success in the University of Glasgow and later in King's College, 

 London. 



Lister is especially noted for the successful introduction of the 

 antiseptic method in surgery which reduced the dangers of infec- 

 tion following operations. This took place in 1867 while he was 

 teaching in the University of Glasgow. This method led to the 

 aseptic method now used the 

 world over, in which opera- 

 tions are performed under 

 sanitary conditions, free from 

 living germs. Lister received 

 honorary degrees from both 

 Oxford and Cambridge, and 

 was made a baronet in 1883. 

 He wrote several books bear- 

 ing on the antiseptic system 

 of treatment. He died in 1912. 



Bell. Alexander Graham 

 Bell was born in Scotland in 

 1847. He was descended from 

 a line of specialists in the hu- 

 man voice. His grandfather 

 invented a system to correct 

 stammering; his father was 

 an authority on elocution and 

 also the inventor of a system 

 of sign language for deaf 

 mutes. 



Alexander Graham Bell 

 early showed both interest and 

 ability in the same field. While still a boy he constructed an arti- 

 ficial skull, which, when operated by a pair of bellows, would pro- 

 nounce certain words. He was educated in Edinburgh and London 

 and afterwards taught elocution for a time in England. Later he 

 came to America for his health. Here he continued certain 

 experiments which gradually led him to consider the problem 

 of transmitting human speech through space. He studied a human 



Brown Brothers.
