Alfred H. Grebe (1895-October 24, 1935) was a pioneer in the radio broadcasting field.

He was born in Richmond Hill in the borough of Queens, in New York City. At the age of 9 he was given a radio set by his father, and soon came to be such an expert that his science teacher at Public School 88 in Jamaica said Alfred knew more than he did. From public school, he went to a training school in Jamaica, and a commercial radio school in Manhattan, New York City, where he conducted his own experiments. By age 15, he became a licensed commercial operator, and went to work as a ship's radio operator. After three years onboard (during which time he traveled as far as India) he returned to Long Island, where the first commercial station on the island was being built at Sayville. He got a job as an operator there. Later, because there was currently a radio craze, some friends had him make receivers for them. After making a few sets, he decided to go into commercial production.

In 1914 he issued his first catalog, and set up a factory in Richmond Hill on the same property where his home was located, which soon became able to produce all the components needed to assemble a radio, and which contained research laboratories as well. By 1922 he tore down his home to build a larger factory on the site.

Alfred Biolek (Alfred Franz Maria Biolek) (born 10 July 1934, in Fryštát, then Czechoslovakia, now Czech Republic) is a well-known German entertainer and television producer. Biolek holds a PhD in law and is an honorary professor at the Academy of Media Arts Cologne.

After expulsion from Czechoslovakia in 1946, the Biolek family moved to Waiblingen near Stuttgart, where Biolek's father practiced law again. Biolek was raised a Catholic and was an altar boy. He temporarily joined later the German conservative party CDU.

He attended the Gymnasium (high school/grammar school) in Waiblingen and graduated in 1954. He then studied law in Freiburg im Breisgau, Munich und Vienna. In 1958 he took a first state exam of law (third-best exam in Baden-Württemberg) and graduated with honors. Biolek worked as a lawyer in his father's office and passed the second state exam. In 1970 Biolek moved to Munich and worked for a larger office. Living in the city, Biolek underwent a radical change and distanced himself from his conservative mindset. He actively participated in the Munich bohemian lifestyle and was part of the film maker Rainer Werner Fassbinder's circle of friends.

John Christopher Howland (born 30 July 1928 in London) is a British radio and TV presenter who opened German radio programmes for English music. Hereby he has changed German radio broadcast which has been dominated by English music ever since.

Chris Howland was raised in Southern England and became a professional beekeeper.

In 1948 he started working for the British Forces Broadcasting Service in Germany. The British programmes were an insider tip for German youths who would rather listen to British music than to the comparatively slow contemporary German pop music. So his popularity subsequently soon exceeded his actual target audience. On the other hand Chris Howland also got acquainted with German language. In 1952, when he already spoke German fluently, he was hired by a German broadcaster. Because of him British music prevails on German radio up to now. Still, when he debuted six years later as a singer , he did it in German and had two hits. But in 1959 he stopped doing radio shows and returned to England.
