First Generation

Joseph Griesedieck was one of the most influential brewers in St. Louis in the late nineteenth and early twentieth centuries. From the 1880s to the 1910s, he helped run several city breweries. At the outset of Prohibition, he acquired the Falstaff label and built the Falstaff Corporation around it. While many other brewers failed during Prohibition, Griesedieck kept his company afloat by selling “near beer,” soft drinks, carbonated water, and pork products. After the repeal of Prohibition, he obtained the first federal permit to begin brewing beer legally again. Within five years, the Falstaff Brewing Corporation was operating four plants in three states and had gained a national market.

Eckhart Grohmann does not fit the all-too-familiar narrative of the old world European immigrant peasant turned captain of industry that permeates much of the American popular memory. Grohmann was already a member of the entrepreneurial class in Germany. After immigrating to the United States, he acquired his own company, Aluminum Casting and Engineering Co., a small Milwaukee foundry that he expanded into a major firm.

After learning the watchmaking trade in the Black Forest region, Dietrich Gruen immigrated to the United States, where he eventually patented an improved center pinion for watches. This innovation became the foundation of Gruen’s business ventures, which included the Gruen Watch Company, a leading watch manufacturing firm that operated for half a century.

Carl Hilmar Guenther established a mill on the Texas frontier in 1851 that grew into one of the largest food processing companies in the nation, producing well-known flour brands such as Pioneer and White Wings, home baking products under the Morrison Mills name, and Sun-Bird and Williams prepared foods. Guenther originally came to America in 1848, seeking greater political freedom and hoping for economic opportunity.

Konstantin Guericke is a web 2.0 pioneer and co-founder of LinkedIn, the world’s largest online business network. Guericke first came to the United States as a high school exchange student and then returned to pursue further studies at Stanford University. Benefiting from a unique environment for innovation, entrepreneurship, and collaboration, he found pathways to Silicon Valley’s high tech start-up scene.

Felix Guggenheim emigrated to the United States in 1940. An influential publisher in Germany, Guggenheim was able to utilize his former contacts to establish a successful business as a literary agent and legal advisor for clients in the U.S. and in Germany after the end of World War II.

Leopold H. Guldman was born in 1852 to Jewish parents in Harburg, a village in the kingdom of Bavaria. After arriving in the U.S., Guldman eventually made his way to Colorado, where he opened small outlets in bustling mining towns and supplied goods to miners. By 1879, at the age of twenty-six, he founded the Golden Eagle Dry Goods Company, which quickly became one of Denver’s leading popular-price department stores.

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.

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.

Jacob Hasslacher has been counted among the American chemical industry’s “founding fathers.” The manufacture and sale of specialty chemicals was more advanced in his native country than in his adopted one, and his firm, the Roessler & Hasslacher Chemical Company, benefited from its German connections during most of the period in which it was led by Hasslacher.

Born in a small town in Bavaria, Isaias Wolf Hellman was one of a number of German-Jewish immigrants whose entrepreneurial and philanthropic efforts helped transform Los Angeles and San Francisco from rough mining camps into two of America’s leading urban centers.

During the first half of the twentieth century, Christian Heurich, Sr., was the most prominent brewer in Washington, DC. He was also regarded as an elder statesman of the American brewing industry as a whole. Born in 1842 in the Duchy of Saxe-Meiningen, Heurich immigrated to the U.S. in 1866 to start his own brewery.

German immigrant Frederick A. Hihn arrived in San Francisco as part of the Gold Rush and later amassed vast landholdings in Santa Cruz County. He spent much of his life developing property around existing towns and creating new vacation communities along Monterey Bay.

Max Hirsch and his son Harold Hirsch were responsible for building one of Portland’s most famous businesses and helping to create a sportswear industry. Max Hirsch was a first-generation German Jewish immigrant to Portland who in 1907 purchased Willamette Tent & Awning from a Portland businessman and turned it into the Hirsch-Weis Company. Building on the success of his father's company, Harold grew his skiwear line into White Stag, one of the largest skiwear companies in the world.

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.

Helmut Jahn arrived in the U.S. as a young architecture school graduate from Germany and, after a meteoric rise in the architectural establishment of Chicago, has enjoyed a steadily successful career. He is best known for large public buildings in urban contexts, such as airports, arenas, and tall office buildings around the world.

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.

Solomon Karpen founded S. Karpen & Bros. in Chicago in 1880. By 1899, it had become the largest upholstered furniture manufacturing company in the world.

Best known for its popularization of the slide rule, Keuffel & Esser was the first American company to specialize in the manufacture and sale of drafting and surveying tools. By the early twentieth century, it was one of the largest manufacturers of scientific instruments in the world.
