Danaher's founders transformed a real estate organization into an industrial-focused manufacturing company. Through a series of mergers, acquisitions, and divestitures, including the Fortive separation in 2016, Danaher now focuses primarily on manufacturing scientific instruments and consumables in three segments: life sciences, diagnostics, and environmental and applied solutions. In late 2019, Danaher separated from its dental business through an initial public offering process, and in early 2020, it acquired GE's Biopharma business, now called Cytiva, which added to its life sciences segment.
