Founding and Leadership

Origins and Charles Engelhard Sr.

Charles W. Engelhard Sr., a German immigrant from , arrived in the United States in 1891 as a sales representative for a European platinum firm, marking the initial roots of what would become a major precious metals enterprise. He began investing in American precious metals companies, focusing on refining and fabrication of , , and silver, which laid the groundwork for subsequent expansion. These early activities capitalized on growing industrial demand for precious metals in , jewelry, and electrical applications during the late 19th and early 20th centuries. In 1902, Engelhard Sr. formally established the business by acquiring the Charles F. Croselmire Company, a small refiner based in , which specialized in precious metals processing. Under his leadership, the firm—initially operating under variations of his name—grew into a key player in refining, importing raw materials and producing finished products for American industries. By emphasizing in sourcing and refining, Engelhard Sr. positioned the company to meet rising needs for high-purity metals amid and technological advancement. Engelhard Sr.'s strategic focus on platinum, a metal critical for early automotive and chemical uses, differentiated the enterprise from competitors reliant on or silver alone. His operations remained centered in until the post-World War I era, when family succession began transitioning management. The founder's death in the 1920s—though exact date unverified in primary records—left a legacy of entrepreneurial acumen in a nascent sector, enabling the company's survival through economic volatility.

Expansion under Charles Engelhard Jr.

Charles Engelhard Jr. assumed control of the family enterprises, including Engelhard Hanovia and Engelhard Minerals & Chemicals Corporation, following his father's death on December 7, 1950. Under his leadership, the business expanded from domestic precious metals refining into a multinational with operations in , chemicals, and applications across 50 countries. In 1957, Engelhard partnered with of Anglo American Corporation to acquire Central Mining and Investment Corporation for $3.5 million, securing a 30% stake in Rand American Investments Limited and control over South African assets valued at $500 million. This deal marked a pivotal entry into large-scale and in . The following year, on January 1, 1958, he consolidated nine operating companies into Engelhard Industries, Inc., taking the firm public on the with initial annual sales of $173 million; the new entity also established the American-South African Investment Company Limited, holding $34 million in assets. Further growth included the 1961 acquisition of two gold mines from Kennecott Copper Corporation for $17 million, integrated into the Rand Selection Corporation. In 1963, Engelhard acquired a 20% interest in the newly formed Minerals & Chemicals Philipp Corporation (MCP) through a stock exchange, providing entry into base metals trading and chemicals with MCP reporting $447 million in sales by 1964. This culminated in the September 1967 merger of Engelhard Industries with MCP, forming Engelhard Minerals & Chemicals Corporation (EMCC), where the Engelhard family retained 40% ownership and diversified into catalysis for petroleum refining, nitric acid production, and applications in automotive, electronics, and aerospace sectors. These moves transformed Engelhard into the world's largest refiner and fabricator of platinum-group metals, gold, and silver. Engelhard died of a heart attack on March 2, 1971, at age 54, leaving the company positioned for continued expansion, with EMCC sales reaching $2 billion by 1972.
