G. Edward Pendray

Record year1930–1970

summaryThrough early articles, a 1945 popular history, and later three-volume editing, organized dispersed rocket history and Goddard's original records into accessible texts.

M rationaleThe three phases produced a continuous delivery of history-of-technology writing and archives without duplicating value from book to book, estimated at M5.3; not having read the full 1945 text limits confidence in its content but does not lower the scale of the delivered text itself.

attribution rationaleG. Edward Pendray .23; Esther C. Goddard .22; Goddard's original writings and technical records .29; AIS/AIAA editorial and archival team .08; original publication team .06; prior work in history of technology and archival editing .06; unresolved share .06. The shares are revisable research judgments.

overlap boundaryCombine the writing/preservation family of the 1930 rocket-history article, the 1945 The Coming Age of Rocket Power, and the three volumes of papers co-edited with Esther Goddard in 1970; the 1945 book is provisionally assessed only from bibliographic and contemporaneous-journal abstracts, and no credit is taken for the technologies it recounts.

Evidence gapsThe 1930 article, the complete 1945 book, and the editorial explanations for the three 1970 volumes have not been read in full; the technical accuracy, reader reach, and chapter-by-chapter sources of the 1945 book remain unresolved.

Record year1936–1939

summaryProvided the Westinghouse world's-fair project with a name of enduring public recognizability and a conception of future reception, and delivered an installed physical artifact.

M rationaleThe naming, public conception, and physical display formed an identifiable cultural-preservation outcome, estimated at M4.8; its corporate-promotional character, unverifiable future reception, and the fact that the engineering was not the sole work of one individual limit its scope.

attribution rationaleG. Edward Pendray .24; Westinghouse time-capsule engineering and content team .31; Westinghouse Electric and Manufacturing Company .13; prior work in time storage such as the Century Safe .20; unresolved share .12. The shares are revisable research judgments.

overlap boundaryCount the 1936–39 ‘time capsule’ term, world's-fair project conception/dissemination, and the 1938 placement of the physical artifact; do not duplicate M separately for the container, materials, and contents, and do not treat the planned opening five thousand years later as an outcome already achieved.

Evidence gapsThe personnel responsible for specific container engineering, materials, and solicitation of contents are unnamed; the individual responsibilities for the 1964 sister time capsule have not been verified and are not included.

Record yearEarly 1930s

summaryIn New York, consolidated spaceflight discussion into an organization of members, meetings, and publications, and began connecting public advocacy with small-scale collective experiments.

M rationaleIt has verifiable joint founding, a continuing forum, and organizational redirection, making it a medium-scale professional public-organization deliverable; M does not assign the rocket engineering of organizational members to the president.

attribution rationaleG. Edward Pendray .14; Leatrice Gregory Pendray .10; David Lasser .10; other AIS founding signatories .25; AIS early journal and experiment team .15; prior work in early rocket and spaceflight societies .16; unresolved share .10. The shares are revisable research judgments.

overlap boundaryCount the twelve people jointly signing to establish AIS in 1930, its public-discussion/journal vehicle, and Pendray's organizational redirection during his 1932 presidency; do not take credit for all the association's experiments, the later ARS/AIAA, the U.S. rocket industry, or military missiles.

Evidence gapsThe minutes of the founding meeting and complete division of work among members have not been read; the association's specific small-rocket experiments and safety consequences are not part of this outcome.
