Mystery solved :: Architect of the Petrolane building on Jefferson Highway was F. Monroe Labouisse
Milton Scheuermann (Tulane School of Architecture class of 1956, member of TSA faculty for 50 years and counting) recollects:
"The building was designed by F. Monroe Labouisse, who at that time was partner in the firm of Goldstein, Parham & Labouisse. In fact, it was that building that made me decide that I wanted to work for the firm and I got my summer job as a 3rd year student with them. I had the greatest admiration for Labouisse.
Leaving New Orleans on Jefferson Highway the building was on the right at the last right turn of the S Curve leading to Ochsner Hospital after crossing the railroad tracks after entering into Jefferson Parish. I actually remember seeing the drawings for the building in the office as well as Labouisse's sketches. I believe there were only 2 or 3 sheets. It made my day!!!"
Thanks Milton! You just made my day.
