Biography Born in Harrisburg, Pennsylvania, Ketchledge married Lois Jane Quackenbush. He earned a B.Sc. and M.Sc. (1942) in electrical engineering from the Massachusetts Institute of Technology before joining Bell Labs where he stayed for his whole professional career (1942–1982). At Bell Labs he first worked on the Mark 24 FIDO Torpedo used in World War II, then took part in developing the first underwater repeater systems and the L-carrier, L3 coaxial carrier for Transatlantic telephone cable systems (1946–54), before becoming the leader of the ''Switching systems'' development group (1956). This brought him fame due to the pioneering work on applying stored program architecture to telephone switching systems. Ketchledge oversaw the installation project for the first 1ESS switch in Succasunna ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Harrisburg, Pennsylvania
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Scientists At Bell Labs
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''
