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 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 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 were the investigation of the Stone Mask, uncovering an ancient mexican temple where the Pillar Man Santana slumbered. The Foundation scientists subsequently sheltered the remains of Santana after his defeat, ensuring that he never left his stone state, and then uncovered a prediction announcing the awakening of three other Pillar Man in the same year. The Special Fighting Technological team from the Speedwagon Foundation, equipped with miniaturized UV lights, helped fight Kars vampiric alongside the German Army, ultimately prevailing against the undead.

The Speedwagon Foundation effectively continued to help the Joestar bloodline throughout the 20th century. In 1988 and 1989, the Speedwagon helped the third Joestar Group reach Cairo, first by providing a crewed ship in Hong King, and then give them supplies in Egypt. Moreover doctors from the Foundation helped taking care of Holy Kujo in Tokyo, and agents of the Foundation in Egypt managed to learn of the existence of the Egypt 9 Glory Gods, and warn the group about them.

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 the prison; after Jotaro Kujo was rendered comatose, the doctors of the Foundation instead took care of his body and cooperated with Jolyne to retrieve the Stand Disks. Finally, agents of the SPW Foundation 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 Stephen 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.
