Frederick William Victor Albert of Prussia was born in Berlin on January 27, 1859. After the death of his father Frederick, he became the last German Emperor and King of Prussia in 1888 as William II.

At the end of the lost First World War, he was forced to abdicate and went into exile in Doorn in the Netherlands in 1918. He died there on June 4, 1941.

During his reign, he refused to implement extensive democratic reforms and consolidated the Prussian monarchy based on military strength.

The spa town flourished at the turn of the century thanks to the Emperor's regular visits to Wiesbaden. In this Wilhelmine era, the May Festival was introduced in honor of Wilhelm and the Kurhaus, the theater and the train station were built. The city districts became larger and the population of Wiesbaden rose to over 100,000 for the first time.

As a sign of gratitude, the city council decided to draw up a Golden Book, in which Kaiser Wilhelm II signed his name as the first guest of honor on May 13, 1902.
