Earl Berling (full name: Ferdinand von Ziberling) was born in Konstanz, Germany on July 8, 1838, and died in Berlin on March 8, 1917. Earl Berling was a pioneer in the German aviation industry and the inventor of large practical hard airships. He graduated from the Louisburg Army Non-commissioned Officer School in 1957 and entered the Tubingen University to study engineering courses in 1858. Later, he served as the guardian of the King of Wattenburg, the Kingdom's envoy to Berlin, and the commander of the cavalry brigade. He retired as a rank of lieutenant general in the army in 1890. He entered the aviation industry very early, as early as during the American Civil War (1861-1865).

Zipperlin, as a military observer of the Northern Federation Army, completed his first balloon launch in St. Paul, Minnesota. After he was discharged from the army, he built the first cigar-shaped aluminum hard airship LZ-1 in 1900. The airship was 128 meters long and 11.7 meters in diameter, and the total capacity of hydrogen airbag was about 11,300 cubic meters. There were two external pods under the hull, each equipped with a 16-horsepower engine. On July 2, 1900, the airship set off from Lake Constance, Germany for its first flight. In 1906, he made two more airships and successfully carried out two speeds of 57.6 kilometers per hour.

Test flight. To this end, the Dresden Institute of Engineering awarded him an honorary doctorate in engineering. Zipperlin was dedicated to aviation. He founded the "Zipelin Airship Company" in 1908. The airships they made were not only used for commercial purposes, but also for military purposes. They installed weapons such as artillery, machine guns and bombs on the airships, bombarded enemy military facilities, attacked submarines, detected minefields and conducted maritime reconnaissance, etc. In the first ten years alone, the company built 113 military airships and showed their power in World War I. Earl Zipperlin also opened the "German Air Transport Co., Ltd." in 1909.

It is said that Delag operates domestic routes and Hamburg-US routes. Their Zipperlin hardships were the world's earliest commercial transport tool for formal airlifts. In 1917, Germany's Zipperlin airships achieved nearly 100 hours of flight twice. The "Earl of Zipperlin" created a flight business across the Atlantic Ocean for the first time. Until it was deactivated in 1937, it flew 590 times, including 144 cross-ocean flights with a mileage of more than 1.6 million kilometers. In 1929, the airship took about 21 days to sail around the world, with a range of about 35,000 kilometers.

Another famous airship manufactured by Zipperlin is the "Hindenburg". The "Hindenburg" is named after the German president at that time. The airship is 245 meters long, with a maximum diameter of 41.4 meters, a total weight of 195.15 tons, a load capacity of 19.06 tons, and a total airbag volume of 200,000 cubic meters. It is equipped with 4 1,100 horsepower diesel engines, with a cruising speed of 121 kilometers per hour and a battery life of 200 hours. The boat is also equipped with a radio station and a telegraph system. The boat is equipped with luxury
