"The existence of two strong schools enhanced New Orleans' reputation, and the result was that both school saw their enrollment increase.  The New Orleans school began in 1856 with a student body of seventy six. ... by 1860 New Orleans had two medical schools equal to the better schools elsewhere, with a total enrollment of 638 students. ... In terms of enrollment the University of Louisiana medical school tied for fourth place in the nation (with the University of Nashville), and the New Orleans School of Medicine ranked seventh. - John Duffy. (1984) The Tulane University Medical Center, p. 28-29.

"The 1850's saw a spirited clash between the faculty of the well-established Medical School of the University of Louisiana and the newly founded New Orleans School of Medicine.  The spokesman for the New Orleans School of Medicine was the recently organized New Orleans Medical News and Hospital Gazette.  The editorial writers of this journal always referred to the faction they represented as "Young Medicine,"  and they constantly contrasted the progressive approach ... with the supposedly conservative attitude attitude of the older group. See: John Duffy, ed. The Rudolph Matas History of Medicine in Louisiana, Volume II. Ante Bellum Period, 1825-1860, p.54.

Dr. Brickell and the remaining few of his cohorts again entered the field of medical education when in 1874 they organized the Charity Hospital Medical College. ... Despite this brave start, the faculty found that New Orleans had not yet recovered to the point of supporting two medical schools, and after struggling for three years the Charity Hospital Medical School followed the New Orleans School of Medicine into oblivion-leaving the field solely in  charge of the Medical Department of the University of Louisiana. Duffy (1957), p.305
