Speedwagon Foundation

The Speedwagon Foundation (スピードワゴン財団) (often abbreviated as "SPW") is a powerful and influential organization created by Robert Edward O Speedwagon, funded by the money he made from the oil he discovered when he visited America. The foundation has helped the Joestars countless times, from giving them private rides that includes but is not limited to; helicopters, submarines, cars and planes. The foundation also has connections with the underworld, namely Passione, and studies many weird happenings from stand users to the Bow and Arrow, the Stone Mask and the Stand Discs.

History
"At the beginning of the century, a lone Englishman by the name of Robert Edward O Speedwagon, arrived in the USA and started his own oil business. Because of this he became one of the world's richest men. Speedwagon decided that after his demise, the large sum of his fortune would be used for medical research and wild animal and plant protection. In this organization exists a department called the Supernatural Research Department, which is responsible for supplying the Joestar Family with everything they need. This was the will of Speedwagon, who died in 1952."

The headquarters of this department is in Dallas, Texas USA, but includes a few offices in Japan as well.

Steel Ball Run
Much like the Speedwagon Foundation in the previous arcs of JoJo's Bizarre Adventure, the Speedwagon Oil Company was founded by a risk-taking entrepreneur striking it rich by finding oil in America. Unlike the previous Speedwagon Foundation, the Speedwagon Oil Company has no connection to the Joestars except for helping to fund Stephen Steel's Steel Ball Run race. It is unknown if Robert Edward O Speedwagon founded this company, though the etymology of the company name seems to indicate he is the founder.
