‎Private photo album of Frank Pepermans illustrating his career as CEO of the Ford Motor Company , afterwards CEO of the Bell Telephone Company, both in Antwerp ( Belgium ) .‎

‎6. Antwerpen, private photo album, 1950 - 1975 , in-folio, oblong format, 30 x 50 cm, contains 50 leaves with a total of 256 tipped on original black/white photographs, photo size varies between 120 x 180 mm and 180 x 240 mm. Bound in green cloth. Finely preserved, only 2 or 3 photographs show some discolouring due to the type of glue used, one photograph partly torn. Most of the photographs are anonymous and obviously made by press photographers. 24 pictures are made by the Brussels' photography agency '' Noir et Blanc '' and illustrate the visit of F.P. at the Brussels' Motor Show in 1960 and 1962. This private album documents the appearences of F.P. in his fuction as ceo, first at Ford and later at Bell Telephone Company. There are pictures of the presentation of the Ford Mercury Montclair at the main Ford dealer showroom in Antwerp ( Permeke ), Merchandising Conferences of the Ford Motor Company, 40th Brussels' Motor Show in 1960 with king Baudouin , prince Albert ( the later king Albert II) and secretary of state Van den Boeynants , with the presentation of the Ford Falcon, Ford Anglia 1960, the 1953 Ford Motor Company 4-letter award, a conference attended by Theo Lefèvre, Paul Henri Spaak, Prince Albert, Jos De Saeger . Oscar Permeke fifty years Ford Dealer ( 1961). In 1963 F.P. switched from Ford to the Antwerp Bell Telephone Company ( later a subsidiary of ITT). Some large pictures of a ceremony where Harold Geneen, president of ITT receives a belgian order of merit from the hands of prime minister Paul Van den Boeynants in the presence of F.P. . Frank Pepermans was an iconic and charismatic businessman who built and strenghtened two U.S. multinational companies active in Antwerp. At the height of his career he became a scape goat in a famous corruption scandal which rocked the belgian political and judicial system. He was accused and sentenced for bribing the socialist run official belgian telephone company ( a state monopoly in those days). He died in suspicious circumstances at a New York hotel. His funeral, which acquired the status of a state funeral, was attended by the acting prime minister Leo Tindemans.‎

In the original printed blue wrappers. With previous owner's name to front wrapper. Sunning to spine and margins of front wrapper. Back wrapper loose. An overall nice and clean copy. Pp. (4), 167-349.‎

‎First printing of Bell Labs Magnetron issue. The Magnetron is a high-powered vacuum tube that through a stream of electrons in a magnetic field generates microwaves. This reduced the size of radar sets which made it possible to install them in anti-submarine aircrafts and escort ships. This had a profound influence on the warfare during WWII. Today magnetrons are commonly used in microwave ovens and in various radar applications.""The studies of Fisk, H. D. Hagstrum, and P. L. Hartman [the present paper] increased the understanding of the role that the various possible modes of oscillation played in magnetron operation and the effect of the wire straps - which later evolved into two pair of concentric copper rings.""

All four articles listed in ""Early Television, A Bibliographic Guide to 1940"". ""The chief problems presented in the accomplishment of television are discussed. These are: the resolution of the scene into a series of electrical signals of adequate intensity for transmission" the provision of a transmission channel capable of transmitting a wide band of frequencies without distortion means for utilizing the transmitted signals to re-create the image in a form suitable for viewing by one or more observers" arrangement for the accurate synchronization of the apparatus at the two ends of the transmission channel.""

‎Physical Principles Involved in Transistor Action. [In: The Bell System Technical Journal, vol. 28, pp.239-277]. - [INVENTION OF THE TRANSISTOR]‎

‎New York: Bell Telephone Laboratories, 1949. 8vo. The entire April issue in original printed wrappers offered. Spine strips with some wear. Small rubberstamp on front wrapper. Otherwise fine.‎

‎First edition. The first comprehensive report to describe the transistor - one of the most important inventions of the 20th Century. The invention of the transistor was first announced in three short letters by Bardeen, Brattain, Shockley, and Pearson, in The Physical Review (Number 2 Volume 74, 1948). The following year Bardeen and Brattain published the more comprehensive report ""Physical Principles Involved in Transistor Action"" [as offered here]. This paper was simultaneously published, the same month, in The Physical Review (Number 8 volume 75). In 1956 Bardeen and Brattain shared the Nobel Prize in Physics with William Shockley ""for their researches on semiconductors and their discovery of the transistor effect"". In 1972 Bardeen again received the Nobel Prize in Physics for his part in the development of the theory of superconductivity (BCS-theory), and thus became the only person, until this day, to receive the Nobel Prize more than once in the same field.
