Lewis W. Leeds (1829-1896) was Special Agent of the Quartermaster-General, for the Ventilation of Government Hospitals during the War; and Consulting Engineer of Ventilation and Heating for the U. S. Treasury Department. "These Lectures were not originally written with any view to their publication; but as they were afterwards requested for publication in the Journal of the Franklin Institute, and there attracted very favorable notice, I believed the rapidly increasing interest in the subject of ventilation would enable the publishers to sell a sufficient number to pay the expense of their publication; and, if so, that this very spirit of inquiry which would lead to the perusal of even so small a work, might be one step forward towards that much-needed more general education on this important subject.
