The story of Linde plc begins not with a grand corporate strategy, but with the intellectual curiosity and persistent innovation of a single individual: Carl Paul Gottfried von Linde. Born in Berndorf, Bavaria, on June 11, 1842, Linde was the son of a German minister and a Swedish mother. Though initially expected to follow in his father's footsteps, young Carl's true calling lay in the burgeoning fields of science and engineering. His early education at the Swiss Federal Institute of Technology in Zurich, where he studied under luminaries like Rudolf Clausius and Franz Reuleaux, provided him with a rigorous foundation in mechanical engineering and thermodynamics. Even an early expulsion from the institute for participating in a student protest couldn't derail his trajectory, as Reuleaux quickly secured him an apprenticeship.

Linde's professional journey led him through various roles in locomotive manufacturing in Berlin and Munich before he found his academic home. In 1868, at the remarkably young age of 26, he became an extraordinary professor at the newly founded Munich Polytechnische Schule (which would later become the Technical University of Munich). By 1872, he had achieved the rank of full professor of mechanical engineering, establishing the first machine laboratory in Munich, a hub of innovation where even a young Rudolf Diesel would later study. It was within these academic halls that Linde’s focus shifted dramatically, laying the groundwork for an entirely new industry.

The world in the late 19th century was grappling with a fundamental problem: how to preserve perishable goods. For centuries, humanity had relied on natural ice harvested in winter and stored in icehouses, a method fraught with limitations and inefficiencies, especially for industries like brewing. Brewers, in particular, faced significant challenges, as the production of bottom-fermented lager beers, a popular and growing market, demanded consistent low temperatures, making year-round brewing nearly impossible without reliable cooling. This was a personal concern for Linde, whose friend, Gabriel Sedlmayr, the president of the German Brewer's Union and from the Spaten Brewery, directly approached him with the challenge of developing a refrigeration system for continuous brewing.

Inspired by these practical needs and driven by his deep understanding of heat theory, Linde embarked on research into refrigeration in 1870. His work built upon the earlier observations of scientists like James Prescott Joule and Lord Kelvin regarding the Joule-Thomson effect—the phenomenon where a compressed gas cools upon rapid expansion. Linde's genius lay not just in understanding the theoretical principles, but in translating them into a commercially viable and efficient machine. He published his initial research findings in the Bavarian Industry and Trade Journal in 1870 and 1871, sparking interest and laying the theoretical groundwork for his future inventions.

In 1873, Linde constructed his first practical compressor refrigeration machine for the Spaten Brewery in Munich, using dimethyl ether as the refrigerant. This early prototype, though a significant step forward, proved to be somewhat problematic due to leaks that could lead to explosions. Undeterred, Linde swiftly moved to develop more reliable systems. By 1874, he had perfected a methyl ether refrigerator, and in 1876, he introduced the first reliable and efficient compressed-ammonia refrigerator. This ammonia-based system was a revelation; it was not only more robust and easier to maintain but also weighed and cost significantly less than its predecessor. This particular machine, weighing almost six tons, was supplied to the Dreher Brewery in Trieste (then part of Austria), marking a true revolution in lager beer production.

The immediate impact of Linde's refrigeration machines was profound, particularly within the brewing industry. Breweries could now maintain precise temperatures, allowing for year-round production of high-quality bottom-fermented beers. This newfound control over temperature dramatically improved the consistency and quality of beer, eliminating the seasonal constraints that had long plagued the industry. Beyond brewing, the potential for refrigeration quickly became apparent in other sectors. Slaughterhouses, cold storage facilities, and food handling businesses were eager to adopt this groundbreaking technology. Refrigeration began to rapidly displace the traditional methods of using natural ice, transforming food preservation and distribution.

The commercial success of his early refrigeration plants quickly consumed an increasing amount of Linde’s time. Recognizing the immense industrial potential of his inventions, Carl von Linde made a pivotal decision in 1879. He resigned from his professorship—which he considered his "ultimate professional achievement"—to fully dedicate himself to his entrepreneurial endeavors. On June 21, 1879, he founded the Gesellschaft für Linde's Eismaschinen Aktiengesellschaft ("Linde's Ice Machine Company") in Wiesbaden, Germany. This act formally marked the dawn of an industrial giant.

The fledgling company, initially focused on the development and promotion of mechanical refrigeration systems, faced a somewhat slow start in a challenging German economy. However, Linde, ever the astute businessman, quickly devised a strategy to accelerate growth: he began to engineer and supply entire ice factories where his refrigeration machines would be installed. This integrated approach ensured a market for his machines and helped establish the reliability and efficiency of his systems. The business picked up quickly in the 1880s, and by 1890, over 700 of Linde's machines were in operation across 445 breweries throughout Western Europe.

The early years of Linde's company were characterized by this initial focus on refrigeration, a business that would prove to be an international success. The impact of his invention extended far beyond breweries, touching industries ranging from dairies and chocolate factories to, somewhat surprisingly, artificial ice rinks. Linde's refrigeration technology was not just about making ice; it was about the precise and consistent cooling of liquids and spaces, a capability that opened up entirely new possibilities for industrial processes and consumer goods alike. The era of modern refrigeration had truly begun, largely thanks to Carl von Linde's pioneering spirit and his commitment to practical, efficient solutions.

By the early 1890s, the company had supplied over a thousand refrigeration machines, and Linde's innovations were rapidly becoming indispensable across Europe. Recognizing the need for continued focus on research and development, Carl von Linde stepped back from the day-to-day managerial activities around 1890 to become a member of the supervisory board. This allowed him to return to his passion for scientific exploration, specifically delving into even lower temperature systems. His foresight and dedication to continuous improvement would soon lead the company into an entirely new realm of industrial innovation: the liquefaction and separation of air, a development that would fundamentally redefine Linde's trajectory and the entire industrial gas industry.
