W. M. Rohrer, vice-president of foreign fertilizer operations, has announced the appointment of Capt. Janusz Grodzicki as director of marine transportation for W. R. Grace & Co.'s Agricultural Chemicals Group. He replaces W. T. McLaughlin who has resigned.

Captain Grodzicki is responsible for coordinating ocean transport of all Grace fertilizer materials to ports throughout the world. The company operates three specially-designed ammonia tankers between its major ammonia producing facility at Point Lisas, Trinidad, and terminals around the world. Dry fertilizer materials are moved in chartered vessels from this location and U.S. ports.

Captain Grodzicki has been affiliated with the maritime industry for 25 years, most recently as manager of marine transportation for W. R. Grace & Co. He held a similar position with Federation Chemicals, Ltd., a company subsidiary in Trinidad, prior to joining Grace in New York in 1964.

Born and educated in Poland, Captain Grodzicki obtained an M.A. in economics at the University of Warsaw where he also studied for his doctorate. He joined the Polish Army during World War II, was wounded and twice decorated for bravery. During the occupation, he escaped to England and joined the Polish merchant navy where he obtained his master's ticket.

After the war, Captain Grodzicki served as a ship's master for five years, and obtained management experience while engaged in the fishing industry in Trinidad for a similar period.
