  1. In your book on the Huey Long Bridge you mention my great grandfather’s pile driving company, E.A. Whitney & Sons. I recall hearing about their driving the piles for the footings from my grandfather, Alton E. Whitney. You also mention the 1941 Final Report on the project. Is there any way I could get a copy of that report?
    I am a graduate of LSUNO, now UNO, as well as LSU where I received my MS in Chem. E. I also have a Ph..D. in Chemistry from the State University of New York at Albany. I worked for Freeport McMoRan and for Crescent Technology in New Orleans as a chemical engineer before retiring.
    Thank you for publishing that book.
