In Memoriam


Lou Nesslar, a certified diver for over 55 years, was an unassuming guy and one of the most experienced and accomplished divers in the Chicagoland area, a true pioneer in sport diving industry. Few divers and instructors have dedicated themselves to the diving community as Lou has.

Lou was certified in 1960 at Lake Geneva. Forget the wetsuit; his check out suit consisted of long johns, two pair of jeans, three wool sweaters and the ever-popular double hose regulator. He served in the Army, an E-4, from 63-65. Lou was located in England and one of his duties was that of a swimming instructor at American Independent Schools. He said it kept him out of KP duty. He lead a team of divers in a competitive British Sub Aqua Club, where he and his first single hose regulator reached depths of 80.
Following his military service, Lou worked his way into the position of a WGN Facilities manager, he personally knew Bozo. He had a second life as a dedicated husband and father. 

 His third life was diving.

He’s certified over 500 divers.

“His ingenuity, fabrication and execution of specialized equipment always amazes the Shedd staff.” “He’s the raw materials/blueprint/schematic guy every aquarium must have to make things go smoothly.” Need a recompression chamber for sea life; just ask Lou. One staff member wrote, “Working with Lou is mind expanding and quite gratifying.” There is a sign hanging up in one of the Shedd’s reserve areas that reads, “No one builds them like mother nature.” A staff member in another area wrote, “Have you met Lou Nesslar yet?”  He has been an outstanding contributor to our sport diving community. There are few individuals who have given as selflessly as Lou Nesslar.
