Victor Posner (September 18, 1918 – February 11, 2002) was an American businessman. He was one of the highest-paid business executives of his generation. He was a pioneer of the leveraged buyout and became notorious for asset stripping.

Posner was born in Baltimore, Maryland, one of nine children of Russian-Jewish grocers Morris and Mary Posner. Though he left school at age 13, he claimed to have earned his first million dollars by the age of 21 by investing in real estate, although financial records do not confirm this.^{[citation needed]}

Taking advantage of the post-World War II demand for housing in America, in 1948, he developed land and built houses in the Baltimore area, and by 1952, was building more than 1,100 dwellings per year. In 1954, he moved to Miami Beach, Florida, where he continued to invest in real estate and publicly traded companies. He became the head of numerous companies over his career, including Security Management Corporation (owner of rental property in Maryland and Florida), DWG Corporation (Arby's and Royal Crown), NVF Company, Sharon Steel, Pennsylvania Engineering Corporation, Salem Corporation, APL Corporation, Evans Products, Graniteville, and Southeastern Public Service Company.

Posner's primary vehicle was the Deisel-Wemmer Co., a cigar manufacturer and importer based in Ohio, which was founded in 1884. By January 23, 1929, Deisel-Wemmer incorporated as Deisel-Wemmer-Gilbert Corporation (DWG) when acquired by an investment group. DWG was a small outfit and just to keep up market share purchased other small cigar companies like Odin cigars in 1930 and the Bernard Schwartz Cigar Corporation in 1939. The Company on May 15, 1946, changed its name to a simple name, DWG Cigar Corporation. Another series of acquisitions started in 1948 with the Nathan Elson Company following with A. Sensenbrenner & Sons in 1955 and in 1956 Chicago Motor Club Cigar and Reading, Pennsylvania-based Yocum Brothers. With the weakening of the cigar market due to medical advisories, many smokers switched to cigarettes, which were then believed to be safer. DWG then streamlined cigar operations and began looking for other businesses that might suit DWG's wholesale and distribution strength. The New York Stock Exchange delisted DWG in 1965, the company then sold their remaining cigar operations or closed them in 1966. Renamed as DWG Corporation, DWG used its cash from the cigar operation sale to purchase a 12% share of the National Propane Corporation. Security Management Company, headed by Victor Posner, a major investor in DWG saw potential with the company as it was bold to sell its main operation. Posner saw it as a good takeover vehicle and became the controlling interest of DWG.

Posner usually placed himself as chairman of the board and president of each company that his Security Management Company subsidiaries, DWG or NVF, a vulcanized fiber manufacturer that controlled the other half of Posner's companies. So while collecting reasonable compensation at each company, Posner's overall compensation surpassed major corporation executive pay like General Motors. NVF controlled Sharon Steel Corporation, one of the country's largest specialty steel manufacturers, which led to legal trouble. Posner sat on Sharon Steel's pension trustee board and directed the pension board to invest in Posner-owned properties. In 1971 the SEC sued, after which Posner then agreed not to sit on any pension board for any of his companies. Posner basically let those companies that could get by with minimum maintenance and nothing more do just that. With a run of acquisitions from 1982 and 1985, DWG faced heavy debt. Posner approached one of his backers, Carl Lindner Jr., for assistance. Instead in 1986, Lindner's American Financial Corporation had acquired warrants for more than 30 percent of DWG's shares. Linder backed down from exercising the warrants but forced Posner to reduce his pay from DWG. Posner also started selling off DWG assets: Foxcroft and Enro shirt groups and the citrus operation. A deal for Royal Crown fell through.

Posner has been an associate of Michael Milken.

An investor that Posner contacted to help get Sharon Steel out of bankruptcy, indicated that his lawyer, Andrew Heine, might want to buy Fischbach Corp. Just short of Fischbach being sold, Heine's Granada Investments Company made a bid for all of DWG at $22 per share. Posner converted all DWG options into voting shares but was unable to vote them due to an Ohio judge's order. Granada sued Posner for not taking the bid seriously and Posner sued back stating the bid had no merit. Posner lost the case in 1991 and was forced to pay $5.5 million to Granada. Furthermore, the judge noting other investigations in illegal stock trading in the Fischbach acquisition and of Posner's compensation added three court-appointed directors to DWG's board as audit, compensation, and intercorporate transactions committees.

Posner stopped the appointed directors from presenting their report to the full board forcing Judge Lambros to convert 50% of Security Management Company ownership in DWG to preferred shares and to sell the remaining common stock. Posner resigned as chair of DWG in 1992 and sold his shares to Trian Group, a New York-based investment partnership led by Nelson Peltz and Peter May. Shareholders agreed to drop their longstanding lawsuits claiming that DWG was raided and stripped.
