Paul Eisler

Paul Eisler was an Austrian-born engineer who invented the modern printed circuit board in the 1940s. This invention allowed electronic components to be connected efficiently on a flat surface, revolutionizing electronics manufacturing. His work laid the foundation for all modern electronic devices, from computers to smartphones. Despite his significant contribution, Eisler's invention was initially overlooked, and he faced challenges in recognizing his impact. Today, the printed circuit board is essential to almost all electronic products, enabling compact, reliable, and cost-effective technology. Eisler’s innovation continues to underpin the modern electronic world we rely on daily.
