In my opinion the best entrepreneur would be Robert S Kerr. He was a wealthy businessman and politician from Oklahoma born in September 11, 1896.
His wealth helped him be part of the senate during the 1930. He worked in the petroleum and natural gas industry and defended the conservation of natural resources.
He is mostly known for a series of water projects and dams that helped make rivers into waterway systems. He also co-sponsored the creation of seven regional water pollution field laboratories, being the most famous The Robert S Kerr Environmental Research Center in Ada, OK, which main goals still nowadays are to protect public health through sustainable health communities, safe and sustainable water resources and chemical safety.
Robert Kerr was not only a wealthy man that only make profit for himself and family but also to help others even after his death.
World War I was started generally because of Franz Ferdinand's death, but there are some background information before this as well.

A = Alliances (Triple Entente and the Triple Alliance; 6 powerful nations gathered into teams and promised to assist each other if war broke out causing a chain reaction)
I = Imperialism (People like to be in control of things, therefore they crave power, they want to take control of others and add the nation's power to theirs)
