José Fernández López was a visionary who transformed Spanish industry with his audacity and innovative spirit. Unafraid of taking risks, he went it alone and invested in two bankrupt industrial slaughterhouses during the Republic. Together with his brothers, he founded the chemical laboratory Zeltia in the early postwar period and gave shelter to scientists who had been persecuted during the dictatorship. He created the first multinational special rail transport company, Transfesa, and patented a track switching system to connect Spain to the European continent by rail through the Pyrenees. He revolutionized fishing with Pescanova's fleet of freezer ships and promoted industrial development with strategic projects such as titanium and lithium extraction. His legacy goes beyond business: his role as a cultural patron and his commitment to Galicia made a difference in the history of the country. This biography reveals unpublished documents and offers an engaging narrative about a man who challenged the limits of his time. With exceptional historical rigor, it rescues the figure of a discreet but influential businessman whose impact still endures. An essential account of an entrepreneur who knew how to stay ahead of his time, build bridges between Spain and the world, and leave an indelible mark on multiple sectors. A story of perseverance, vision, and legacy that deserves to be told.
