Dr Drennan was a visiting physician to the Belfast Poor House.  He sought permission from the board to trial a smallpox inoculation on the children in the house 16 years before Edward Jenner published his paper on inoculation.

Dr Drennan was a man of many talents and this new exhibition in Belfast seeks to highlight just some of them.
