Company History and Business Evolution

The origins of GlaxoSmithKline trace back to the 19th century, with the founding of individual companies that would later merge to form the modern GSK. In 1715, Plough Court pharmacy was established in London, which eventually evolved into the pharmaceutical company Glaxo. Meanwhile, in 1830, Smith Kline & French was founded in Philadelphia, focusing on prescription medicines. Over the decades, these entities grew through strategic acquisitions and innovations. In 1880, Smith Kline & French introduced the first mass-produced pharmaceutical product, the Greenstone brand. The 20th century saw significant milestones, including the development of the first genetically engineered human insulin in 1982. In 2000, the merger of Glaxo Wellcome and SmithKline Beecham created GlaxoSmithKline, forming one of the largest pharmaceutical companies in the world. Since then, GSK has continued to expand its portfolio through acquisitions like Stiefel Laboratories (dermatology) and Human Genome Sciences (biologics). In recent years, GSK demerged its consumer health division into Haleon in 2022, sharpening its focus on biopharmaceuticals and vaccines. The company's evolution reflects a relentless pursuit of scientific breakthroughs, with a current pipeline centered on immunology, oncology, and gene therapy. This extensive history establishes GSK as a cornerstone of modern medicine.
