In 1935, Charles followed his father into the Spreckels family businesses, starting out in sales for $150 per month (about $3,500 per month in 2025 dollars), rising to the position of western sales manager by 1942. His business career was interrupted by the outbreak of
World War II when he joined the
United States Navy and served from 1942 to 1945. He held the rank of
lieutenant commander, serving aboard the
USS Bunker Hill in the
Pacific theater.
Leadership of Spreckels Companies Returning to the Spreckels companies after the war, Charles de Bretteville quickly rose through the ranks as an executive. In 1947, he took his father's seat on the board of directors of the Spreckels Sugar Company and soon after became vice-president of the J. D. and A. B. Spreckels Company, as well as president of three Spreckels sugar cane plantation interests, the
Hakalau Sugar Plantation Company and
Kilauea Sugar Plantation Company in Hawaii In 1950, the
American Sugar Refining Company, which already held 50% stake in the Spreckels Sugar Company (an arrangement that went back to Claus Spreckels founding of the company) bought out Blair Holdings' 40% stake of the Spreckels companies, leaving it as the largest shareholder of Spreckels Sugar overall and a significant minority interest in the Spreckels Companies. American offered to buy out the remaining shareholders, but the offer was rebuffed. In 1951, de Bretteville became president of the Spreckels Sugar Company. De Bretteville stepped down as Spreckels Sugar president in 1962 and sold his stake in the Spreckels Company to the American Sugar Refining, allowing it to fully take over the companies. Spreckels Sugar Company was then merged in as a division of that company, rebranded as the American Sugar Company. One way that de Bretteville attempted to stimulate growth was to bring in new investment, and one of the investors that he courted was French banking magnate
Baron Edmond Adolphe de Rothschild, who ended up purchasing 17% of BanCal Tri-State Corporation, the holding company that owned the Bank of California. Nevertheless, he would remain a board member of the bank for another two years. == Later activities ==
