Otto Lilienthal (May 23, 1848 – August 10, 1896) was a German pioneer of human aviation who became known as the Glider King. He was the first person to make well-documented, repeated, successful gliding flights. He followed an experimental approach established earlier by Sir George Cayley. Newspapers and magazines published photographs of Lilienthal gliding, favorably influencing public and scientific opinion about the possibility of flying machines becoming practical. For his contributions to the field of aviation at such a crucial time he is often referred to as "The Father of Flight."

Lilienthal was born in Anklam, Pomerania Province, Prussia. He attended grammar school in Anklam, and also studied the flight of birds with his brother Gustav (1849–1933) . Fascinated by the idea of manned flight, Lilienthal and his brother made strap-on wings, but failed in their attempts to fly. He then attended the regional technical school in Potsdam for two years and trained at the Schwarzkopf Company before becoming a professional design engineer. He would later attend the Royal Technical Academy in Berlin.

Reinhard Friedrich Michael Mey (born December 21, 1942, Berlin) is a German singer-songwriter, known to fans as "Liedermacher". In France he is known as Frédérik Mey.

Mey has released 27 German albums so far by 2009, and consistently releases a new album approximately every two years; his first album was Ich wollte wie Orpheus singen (1967); the most recent studio album is Mairegen (2010). His biggest success to date was Mein Achtel Lorbeerblatt (1972). His most famous song by far is "Über den Wolken" (1974), which has been covered by numerous German artists. Mey is known to embark upon an extensive concert tour every two or three years, with a live album released from each tour.

Reinhard Mey was born on December 21, 1942, in Berlin, Germany, where he spent his childhood. At the age of twelve, he had his first piano lesson, and at the age of fourteen, he got his first guitar. He taught himself how to play the trumpet. During his school years he gained performance experience by playing Skiffle music with friends. In 1965, Mey was offered the chance to perform at a Liedermacher festival at Waldeck Castle, a converted castle ruin. This led to his first recording contract. In 1961, he became part of the group Les Trois Affamés, with Schobert Scholz.
