JOHN FRIES FRAZER 

 Born, July 8, 1812; died, October 12, 1872 



The career of John Fries Frazer was largely connected with 

 the city of Philadelphia. He was the son of Robert Frazer, an 

 eminent lawyer, and was born on Chestnut Street, opposite Inde-

 being professor in the High School of Philadelphia for some

 his death, when, from being the youngest member of the faculty, 

 he had become senior professor and Vice-Provost.

 lectures were delivered with enthusiasm and enlivened by many 

 anecdotes, and roused the deepest interest in the students. At 

 the Franklin Institute, also, he carried on, with great satis-

After his marriage in 1838, his house became a center of 

 social and intellectual intercourse. He had assembled a large
