Edward J. O'Callaghan, M.D. 

U.S. Navy Assistant Surgeon Application

 

By Norman L. Herman, M.D., Ph.D.

The following is a dictated translation of the hand-written application to the U. S. Navy Examination Board during the Civil War by a civilian physician/surgeon for a position as a medical officer in the Federal Navy or for promotion to Assistant Surgeon by an Acting Assistant Surgeon.  The actual applications are in the possession of the author and presented to enlighten the general public and other researchers as to the education process before and during the Civil War, the personal history of the applicants, as well as to show their personal level of medical knowledge in answering the questions asked by the Navy Board of Examiners.  (Some applicants failed to pass and did not serve or served in the Union Army.)

This written presentation was first of a part of a two-part exam consisting of a written exam and an oral exam.   Many of these applications are rich with highly detailed medical content offering an interesting perspective on the medical knowledge and practices of the period.  A broad sampling of these exams is presented to give you a 'picture' of the type of applicant being examined and admitted to or rejected by the Federal Navy in 1863.   Much more detail on the individuals and their personal and naval history will be presented in a forth-coming book by Dr. Herman.

(The actual written exam photos are available, but not presented on these pages due to the size of the files.  An example of a hand-written exam is on the 'List of all Applicants' page)

If you have additional information or images for any of these doctors, please contact us.

Sir:

   

I, Edward J OCallaghan was born on a third of May 1839 (in Listowel Ireland): up to the age of 12, I studied under a tutor at home, I then went to a boarding school called St Marys College in Kingston Island near Dublin, where I remained two years.  I then went to the College des Josphites, in Louvain in Belgium where I remained two years a student in arts. 

 

I commenced the study of Medicine in 1858 at Stevens Hospital in Dublin where I remained for 3 years after which I attended one session at the Queens College in Cork of which I was a matriculated pupil. during vacation I had a good deal of dispensary practice at home, and have compounded medicine at the District Dispensary.  I have been a Surgeons Steward in the U.S. Navy for one year during which time I had an opportunity of seeing several gun shot wounds and two postmortem examinations trusting that this account of my studies and experience in medicine will prove satisfactory

                                   

I have the honour to be

Yours most Respectfully

Edward J. OCallaghan.
