Hirschhorn succeeds Blaustein at helm of American Trading

January 11, 1991

David Hirschhorn has been elected chairman of American Trading and Production Corp. of Baltimore, filling a position left vacant when Morton K. Blaustein, the company's chairman and chief executive officer, died unexpectedly last month.

Hirschhorn, who has been with the company for 32 years, has served as president, chief executive officer and vice chairman of the board.

Louis B. Thalhelmer, who has worked for the company for 10 years and served as senior vice president, president and chief operating officer, was elected president and chief executive officer.

Mary Jane Blaustein was elected as a director to fill the vacancy left on the board by the death of her husband.

Morton Blaustein died Dec. 17 after choking on food while eating at a hotel restaurant in Richmond, Va. He was 64.

Hirschhorn is married to Blaustein's sister, Barbara.

Along with his son, Jacob, Louis Blaustein opened the first drive-in gas station, invented the first metered gas pump and developed anti-knock gasoline. The American Oil Co., now known as Amoco, later merged with Standard Oil of Indiana.

The family's business activities were later merged into the American Trading and Production Corp., which Morton Blaustein ran for the last 20 years.

American Trading owns and operates a fleet of ocean-going tankers, explores for and produces oil and natural gas, develops real estate, manages office parks and is involved in various forms of manufacturing, according to information provided by the company.

American Trading has 1,300 employees, including about 250 in Baltimore. The company owns real estate in Baltimore, the Washington area and Southern California.

The company also holds substantial shares of stock in Crown Central Petroleum Corp.
