William Francis Roelofson (Bill) Griffith III (July 16, 1934 - December 14, 2025)
Mary Ann Helen Beiser (Mary Ann) Griffith (January 4, 1935 - January 4, 2026) 

Bill Griffith and his beloved wife, Mary Ann, passed away three weeks apart in Ponte Vedra Beach, Florida, both at the age of 91. Their love story, spanning more than 70 years across the country from Arizona to Florida, has moved for the final time to the other side of the rainbow. Their life was one big adventure, including large extended families, four children, three grandchildren, numerous friends, ruckus rodeos and a corporate career. Their 30+ years of retirement afforded leisure time and pleasure in yachting, traveling and socializing with friends at their beach club. They especially enjoyed the Atlantic Ocean view from their Ponte Vedra Beach condo during their Golden Years.

Bill was born on July 16, 1934, in Tucson, Arizona, at the Stork's Nest to William F.R. Griffith, Jr. and Suzanne Bradley Griffith. He attended the University of Arizona, where he was Rodeo Boss and graduated as a proud “Aggie” in 1956. He married Mary Ann Beiser on January 28, 1956. Mary Ann was born on January 4, 1935 in Oak Park, Illinois, to Frank D. Beiser and Margaret O’Toole Beiser. She also attended the University of Arizona and lassoed her cowboy at a rodeo dance held at Li'l Abners by writing her phone number on his sleeve.

In the early years of marriage, Mary Ann was a traditional homemaker who enjoyed cooking, sewing, making pottery, restoring antique furniture and weaving.  She battled blindness for most of her life but did not let it slow her down. She raised four children with a strong moral foundation and work ethic. The eldest of six siblings, she had leadership skills and a strong personality that were the driving force of the family. She was an influential navigator of their life together.

In the early 1960s, Bill launched his corporate career selling agrichemicals and fertilizers to farmers in Arizona and California. He moved on to Eli Lilly subsidiary Elanco Products for 10 years, where he was involved in the introduction of several important products. He also worked for the German chemical giant BASF for a couple of years. Bill’s 18-year career with American Cyanamid were his most professionally satisfying. He was VP/GM of the billion dollar agrichemical subsidiary and was named NAMA 1991 Agri-Marketer of the Year. In 1994, American Cyanamid merged with American Home Products and Bill retired at the age of 60.

His colleague and friend Kenneth Root wrote, “Bill was considered a great leader in the Agri-Chemical industry. He worked at American Cyanamid in the 1980’s and ‘90’s as Vice President of Crop Protection Chemicals. He was instrumental in starting the AgriCenter concept of direct marketing and funded the startup of the National AgriChemical Retailers Association (NARA). He was a strong competitor but a great friend of fertilizer and crop protection companies across the spectrum. He retired to a quiet life with his wife over a quarter century ago but his work and legend live on with those who knew Mr. Bill.”

Bill was also a volunteer board director of XSInc from 1997-2019. He was proud when XSInc merged with TK to became TKXS and within a year purchased by Telus. He also served on Gowan Company board of advisors, Ocean Villas at Serenata Beach Condo Association board of directors, as a commodore for Queens Harbor Yacht Club and “President for Life” of Griffith Aquasports Co. A proud descendant of numerous colonial families, Bill was a member of the Society of the Cincinnati.

Bill enjoyed annual cruises from St. Augustine, Florida, to Abaco Islands on his yacht DreamTime, including a few solo passages, and a transatlantic crossing on a sailing yacht. His last adventure was traveling up the Amazon River at 85-years old with his daughter, Kate. He was a dedicated family man.

Griffith IV, Thomas Griffith (Karen), Aline Griffith (Barrett Gould); grandchildren John Griffith, Jake Griffith, Matt Griffith; Bill’s siblings Charles Griffith (Barbara), Johanna Bradley; Mary Ann’s siblings Jane Dolan (Bob), Larry Beiser (Cindy), Margery Wingfield, Darr Beiser (Margo Warren).
