The Danish inventor Valdemar Poulsen developed the first magnetic tape recorder, the telegraphoon, in 1898. A few years later, the Dane also made the very first answering machine for the telephone. The answering machine allowed callers to leave a message when their call went unanswered. Today voicemail systems are the most normal thing in the world, but in the early twentieth century this was still a new phenomenon. The telephone itself was also only a few decades old.

German chemist Felix Hoffmann went down in history as the man who gave the world the Aspirin. The painkiller consists of acetylsalicylic acid. The effect of that substance had been known for much longer, but Hoffmann marketed it under the name Aspirin in 1899, which made it extremely popular.
