How many companies did Rockefeller own?
John D. Rockefeller founded the Standard Oil Company in 1870. He retired in 1897 and his son, John D. Rockefeller Jr, took over the company for his father. They worked to further their business endeavors through Standard Oil alone (though Junior piloted many endeavors with the Chase's).
J. D. Rockefeller was considered both a robber baron and a captain of industry. No he wasn't, he was simply a man that knew how to invest and make sure that his companies were prosperous. He was a philantropist who gave back to many organizations and colleges. Rockefeller gave 10% of every paycheck to Baptist churches. (to above answer) YES he was a robber baron since not only did he invest well, his original wealth…
Yes. Mormons are quite often known for their entrepreneurial spirit and many Mormons own their own companies. Utah has the highest percentage of Mormons and also one of the highest percentages of start-up companies and small businesses. The Church itself owns very few for-profit companies. These include Deseret Book (a religious book store) and Deseret Management Corporation (a real estate and property management group).
