Matthew J. Marks, 87, international trade lawyer who spent 33 years with the U.S. Treasury Department working out agreements to protect businesses here and abroad, died May 1 in Hanover, N.H.

Marks, who rose from junior attorney in 1941 to deputy assistant treasury secretary for tariff and trade affairs in the Nixon administration, helped devise the 1970s duty laws that precluded dumping of competitive foreign products on the U.S. market.
