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 E. O. Speedwagon, funded by the money he made from the oil he discovered in America. The foundation dedicates itself to medical research and environmental conservation, but it has also helped the Joestars countless times through intel, supplies, and backup. The foundation also has connections with underworld groups such as Passione, and studies many supernatural phenomena such as the Pillar Men and Stands.

History
"At the beginning of the century, a lone Englishman by the name of Robert E. 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.""

Their first noted action was the investigation of the ancient Mexican temple where the Pillar Man Santana slumbered. Foundation scientists subsequently sheltered the remains of Santana after his defeat, and uncovered a prediction announcing the awakening of three other Pillar Man in the same year. The foundation's Special Fighting Technological team also fought alongside the Germans against Kars' vampire army.

The Speedwagon Foundation effectively continued to help the Joestar bloodline throughout the 20th century. In 1988 and 1989, they aided the third Joestar Group in reaching Cairo, through reconnaissance intel and various modes of transportation. Moreover doctors from the foundation helped taking care of Holy Kujo in Tokyo, while agents in Egypt discovered the existence of the Egypt 9 Glory Gods. They tended to the team's injuries at the end of their journey, most notably in helping revive Joseph Joestar.

In 1999, the Speedwagon Foundation led by Jotaro Kujo first escorted Joseph Joestar to Morioh and then were given the Bow and Arrow for study and protection. In 2011, the SPW Foundation provided a submarine for Jolyne Cujoh's escape from Green Dolphin Street Jail. After Jotaro Kujo was rendered comatose, the doctors of the foundation tended to his body and cooperated with Jolyne to retrieve the her father's stand and memory Discs. They also threw a special spear toward the Kennedy Space Center, which combined with Ermes Costello's Kiss, enabled her and Jotaro Kujo to reach Enrico Pucci.

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 Steven Steel's Steel Ball Run race. It is unknown if Robert E. O. Speedwagon founded this company, though the etymology of the company name seems to indicate he is the founder.
