First Generation

Hackfeld, Heinrich

Heinrich (Henry) Hackfeld was born in Almsloh, a village in the parish of Ganderkesee, in the Grand Duchy of Oldenburg. He eventually became part of the Bremish mercantile elite, but was atypical in that he came from a humble background. His firm, H. Hackfeld & Co. of Honolulu, was one of a number of German mercantile businesses founded in Melanesia and Polynesia during the nineteenth century. Initially the main focus of the firm’s business was both indirect and direct involvement in the North Pacific whaling industry. After the demise of this industry, at the beginning of the 1870s, the firm shifted its focus to another part of its business, the provision of factoring services to the Hawaiian sugar industry. By the time of the incorporation of Hawaii as a United States Territory in 1900 the firm was one of a small group of sugar factors that dominated the islands’ economy.

Hammer, Adam

Adam Hammer was a German physician who immigrated to St. Louis, after having participated in the uprising in Baden. Soon after his arrival in the United States he became aware of the deficiencies in the American medical education system. He determined that the most effective remedy for the situation would be to carry out a comprehensive reform of the medical sector using the educational and medical practices of Germany as a model. Hammer’s entrepreneurial significance is found in his contributions to society as a social entrepreneur in the worlds of academia and public health, rather than as a profitable commercial entrepreneur.

Hohner, Hans

In 1857, Matthias Hohner established a harmonica workshop that would become the world-leading producer of this small musical instrument. Founded in Trossingen, a small town in rural southwest Germany, the company soon expanded into the American market through Matthias Hohner's son Hans, who was partially educated in the United States and supervised the first foreign branch of the company, founded in New York in 1901. Hans' nephew, Matthias (Matthew) Hohner, later took over the American branch from Hans in 1927.

Jesselson, Ludwig

In the decades after 1945, Philipp Brothers grew to become the largest and most important metal trading company in the world. By the late 1970s, the company had become an international giant, dealing in over one hundred and fifty different industrial raw materials with representatives in virtually every country in the world possessing metals or minerals of commercial quality. During most of this period, Ludwig Jesselson, who had come to New York in 1937 to work for Philipp Brothers, was at the helm of the company. Jesselson led the company from a sizable private company to an international giant, in the process contributing to changing the markets for international commodities.
