The man who inspired iconic Nintendo character Super Mario died at the age of 84.
Nintendo named their moustached plumber after property developer Mario Segale after renting a warehouse from him in the 1980s.
Mr Segale, from the US state of Washington, passed away on October 27 surrounded by friends and family.
Despite his video game fame, his obituary revealed he "always ducked the notoriety and wanted to be known instead for what he accomplished in his life".
The developer leaves behind wife Donna, four children and nine grandchildren.
In the 1980s, the Italian-American businessman leased a warehouse to Nintendo of America who decided to name the star of their new video game after him.
According to one story he once walked into the building demanding to know where the rent was.
To placate him he was promised to be added to a game.
They then used Mario on the western version of Donkey Kong to replace the generic name of Jumpman.
Mr Segale joked in 1993 he was "still waiting for my royalty cheques".
Born in Seattle to first generation Italian immigrant farmers Louis and Rina, the developer went on to build a property development business.
After graduating from high school, he started his own construction company with just a single dump truck. His firm Segale Properties went on to huge success.
His obituary stated: "Although he took little time away from work, Mario loved hunting, fishing, his airplane, a good joke, the color red, great Italian food (with no cheese!), an excellent cigar and his view of Puget Sound.
"His passion was figuring out how to do things in new and better ways, which often included drawing things on the backs of napkins and placemats.
"The innovations he brought to the construction industry that are still seen today attest to his remarkable creativity."
The Mario series is often cited as the most successful video games franchise of all time.
The plumber's latest adventure, Super Mario Odyssey, is currently the best-selling game on the new Nintendo Switch console and has sold more than 12 million copies.
