On 15 May 1891, merchant and banker Frederik Philips (1830–1900) and his son, mechanical engineer Gerard Leonard Frederik Philips (1858–1942), founded the firm Philips & Co. as an incandescent lamp factory (Gloeilampenfabriek) in Eindhoven, Province of North Brabant, Netherlands. The location was an affordably acquired vacant factory building in Eindhoven. Production commenced in 1892, initially reaching around 200 light bulbs per day; in 1893, Gerard Philips developed a process for manufacturing high-quality filament lamps, raising output to around 45,000 units per year. In 1895, his younger brother Anton Frederik Philips (1874–1951) joined the firm as a sales representative and drove international distribution. By around 1900, Philips was already among the largest incandescent lamp factories on the European continent. The firm's economic rise transformed Eindhoven into the Dutch "Lichtstad" (City of Light).
