and Endre Rédl - both born in December 1906. One worked in Hungary and the other abroad, but both names are etched into Hungarian technological history. Gábor Heckenast Jr: The birth, flourishing, and slow demise of the rust-brown ribbon The first magnetic sound recording was demonstrated at the 1900 World’s Fair in Paris by Waldemar Poulsen of Denmark, whose recorder used steel wire to carry the sound. The first real change in sound recording came in 1928, with a patent registered by F. Phleumer, an Austrian living in Dresden, who attached ferric oxide powder that could be magnetized to a strip of cellulose, creating a medium on which it was easier to record sound. The first K 2-type tape recorder based on his patent was made in 1934. After discussing events leading up to the magnetic strip, the author goes on to give a history of sound recording from the very beginnings to today. He describes the birth of the rust- brown ribbon or tape, the spread of tape recorders operating with high-frequency magnetic heads, the various spool tape recorders and cassette recorders, and the many different kinds of tape. He goes on to report the global conquest of the compact cassette, the advance into simultaneous image and sound recording, and the takeover by the compact disk (CD), followed by the MP3 and the pen drive. Projecting the future, he predicts that the market for non-deletable memories will soon see the appearance even smaller, even faster, and even higher capacity chips. Ibolya Bartók: Anniversary exhibit at the Postal Museum As manager of the Postal Museum’s data archives, the author began collecting and processing the documents with information on the museum’s history when she started reorganizing and systematizing the collection in 2002. Since initially she had very few original documents to work with, she also researched document archives and studied documents in related museums. In 2006, to mark the 125th anniversary of the establishment of the Postal Museum collection and the 110th anniversary of the Postal Museum itself as recipient of the collection, she designed a temporary exhibit called History of the Postal Museum. The display, which marked the double anniversary, presented events of the past 125 years through the major work of Postal Museum leaders and the lives and work of the post office personnel who played major roles in establishing the museum, and in the history of the museum. Through a series of tableaux, we can learn about these well-known figures in postal history, finding out who they were, what they did to establish the museum, and who managed the museum after 1955. She describes how the collections grew under their management, and how the nationwide network of branches came about. Ildikó Makkai-Várkonyi: Letterboxes used by the Hungarian post office This article covers the letterboxes set up in public places to collect mail people wanted to have delivered, from their first appearance in the 16th century, their spread in the 19th, and history up to and including 1945. The first such boxes were made of wood and placed outside churches, and the modem ones are metal and designed for quick and secure transfer of the letters to carrier bags for transfer to post offices.
