William Goman "Bill" DePierri Jr.
1930 - 2020
William "Bill" Goman DePierri, Jr., a longtime resident of Baton Rouge, passed away peacefully while surrounded by family on Sunday, March 15, 2020. Born in Nashville, Tennessee on August 24, 1930, Bill received both a B.S. degree and a M.S. degree in Chemistry from Vanderbilt University, where he lettered in fencing and was a member of Sigma Nu Fraternity. He also earned a PhD in Organic Chemistry from the University of Illinois where he was a member of the Phi Beta Kappa Society. He then worked as a chemist for ExxonMobil for 40 years, obtaining numerous patents for his inventions. Bill is survived by his children, daughter Shawn DePierri Miller and husband Thomas Miller, Jr., son Robert DePierri and wife Michelle Millet DePierri, son Thomas DePierri and wife Trudy Babin Avrill DePierri, grandchildren Thomas "Trey" Miller III and wife Rachel Roberts Miller, Olivia DePierri, Danielle DePierri, Tiffani Avrill Theriot and husband Brandon Theriot, Jeremy Avrill, Matthew Avrill and wife Mary Podorsky Avrill, and great-grandchildren Slayde Theriot, Ty Theriot, Kayne Theriot and Camden Avrill. He was preceded in death by his mother, Elizabeth Maurine Hooper DePierri, father, William Goman DePierri, and his loving wife of 56 years, Ellen Hansen DePierri. Bill was a brilliant man with an insatiable thirst for knowledge and a hands-on approach to life, as evidenced by his multiple home improvement projects. Along with his wife Ellen and their children, Bill loved to travel, especially throughout the American Southwest. An avid tennis player, he quite enjoyed beating "flat bellies" – especially as a middle-aged man. Bill was active in the community through a number of organizations including the American Chemical Society, the American Institute of Chemical Engineers, Fleur de Lis, ExxonMobil Annuitant's Club, Gourmet Club, and Cajun Clickers. He was adored by his family for his positive outlook on life, often saying "you can go through life happy, or you can go through life sad – it all costs the same!" Due to the current coronavirus (COVID-19) pandemic, a memorial will be held to celebrate Bill's life at a later date.

I was privileged to work for Bill for many years at the lab. His folksy, offhand manner and witty aphorisms could sometimes mask the razor-sharp intellect he brought to bear on any challenge. I personally looked up to him, and will never forget the bright light he shone on our workplace and our community. My sincere condolences to the family.

Bill helped recruit me to work for Exxon at Baytown. I also had the good fortune to work with Bill at Baton Rouge. Bill was an all-round good guy and very wise. I benefited from my relationship with Bill.
My condolences to his Family.

Your father was an amazing man and I witnessed his kindness each and every day during his time at St. James
as he engaged with friends and staff. When we spoke about family he beamed from ear to ear....I know he is looking down from heaven with a big smile on his face knowing that his family left on earth will continue to make him proud! WELL DONE Mr. Bill, WELL DONE!

Hi Bob - I saw your Father's obit in the paper and wanted to contact you. I didn't know your Father, but certainly heard a lot of good things about him over the years. Are you still working? I can't believe I'm coming up on 6 yrs retired. I hope you and your family are well. Anne and I are fine. You can get me at [email protected] Let's get a lunch after this corona virus clears.

Mr. Bill was such a sweet man. He moved into St James about the same time I became the Life Enrichment Manager(Activities) and loved his loving kindness and friendliness. He always greeted me when I saw him and was quick to start up a conversation. I was very blessed to know him. My sympathy goes out to his family.
