The Maceos soon controlled most of the gambling, prostitution, and other vice on the island. Their wealth and Sam's ability to deal with influential figures allowed him to exert increasing influence over other businesses and the government of the island. The syndicate created by the Maceos quickly became a business empire. Through business dealings and partnerships Sam Maceo was able to earn millions for the syndicate. However, though Sam was generally the public face of the syndicate, Rose is generally credited as being the boss. The headquarters of the Maceo syndicate was the Turf Athletic Club. In addition to gymnasium and steam room facilities the club contained a bookmaking parlor for baseball and horse race betting as well as two clubs, the Studio Lounge and the Western Room. The business empire included dozens of bookmaking parlors, casinos, and clubs throughout the island and Galveston County, particularly Kemah and Dickinson. Additionally the Maceos came to dominate vice and narcotics as far north as Dallas. The crown jewel of the Maceo empire was the Hollywood Dinner Club. Once the Hollywood was shut down by the Texas Rangers in 1939 the Balinese Room became the premiere club in the syndicate's holdings. Other properties held by the Maceos included the Moulin Rouge, Murdoch's Bingo, and the Pleasure Pier. Investments in oil speculation helped to diversify the Maceo's portfolio and add to their wealth leading to the creation of Gulf Oil Properties. Other Maceo corporate holdings included Maceo and Company, Dickinson Equipment, Murdoch Bathhouse Company Inc., Gulf Coast Properties Inc., Gulf Entertainment places, and the Galveston Novelty Company. Maceo cultivated relationships with business leaders throughout Galveston including William L. Moody, head of one of Galveston's most prominent families. Over the years Sam was able to secure substantial financing from Moody's American National Insurance Company (ANICO) and many other institutions. Maceo established strong relationships with the blessing from leading families such as the House of Sealy and the Kempner family. Major "legitimate" businesses on the island such as the Sealy's banking, premier Hotel Galvez were, in fact, able to thrive in large part because of the illegal activities permitted and including access to the Galveston Wharves and shipping terminals owned by the House of Sealy. The Maceos did not own all the major vice businesses on the island. Though dominant figures in many ways, they generally did not attempt to prevent others from prospering so long as it did not interfere with their businesses.
