The complete life story of Hans Liebherr, the German master builder who invented the mobile tower crane and built one of the world's largest machinery empires from nothing. Born in 1915 in Bavaria, Hans lost his father in World War I when he was just two years old. Raised by his stepfather in the construction trade, he survived the Eastern Front of World War II and returned home to a devastated Germany. In 1949, working in a small wooden shed with local blacksmiths, he invented the TK 10 — the world's first mobile tower crane. When he exhibited it at the Frankfurt Trade Fair, he received zero orders. Most men would have quit. Hans Liebherr didn't. This video covers his entire journey: from fatherless child to wounded soldier, from struggling inventor to industrial titan. We explore how he created Europe's first hydraulic excavator, entered the refrigerator business, expanded to Ireland, built luxury hotels, and established a management philosophy that kept his company debt-free for decades. By the time of his death in 1993, the Liebherr Group employed 15,000 people across 46 companies with $2.5 billion in annual sales. Today, it employs over 50,000 people and generates €14 billion in revenue. It remains 100% family-owned. This is the story of Hans Liebherr — master builder, inventor, and one of Germany's greatest post-war entrepreneurs.
