Paul Dyer Merica

Paul Dyer Merica (March 17, 1889 – October 20, 1957) was an American metallurgist, president of the International Nickel Company of Canada Ltd., inventor, and recipient of the 1938 John Fritz Medal.

Biography Youth and education Merica was born in Warsaw, Indiana, to Charles Oliver Merica and Alice White Merica. After attending the Warsaw Community High School and three years at DePauw University, he obtained his AB from the University of Wisconsin in 1907.

In 1919 he moved into the industry to the International Nickel Company, where he developed the first of the Inconel alloys (Inconel 600) to protect the nickel cookware market against competition by stainless steel.

Among his seminal contributions to the science of nickel were his 1924 study with Waltenberg on the non malleability of the metal. He was able to ascertain that the presence of sulfur is responsible for the property, and thus he was able to explain the 1879 work of Theodor Fleitmann.

He started as Director research, and worked his way up to Technical assistant to president in 1929, and furthermore to executive vice president, president and director and in 1951 the gold medal of the American Society for Metals.
