Document 3: Wallace D. Hayes: Wallace D. Hayes (b. September 4, 1918 – d. March 2, 2001) was a professor of mechanical and aerospace engineering at Princeton University and one of the world's leading theoretical aerodynamicists, whose numerous and fundamental contributions to the theories of supersonic and hypersonic flow and wave motion strongly influenced the design of aircraft at supersonic speeds and missiles at hypersonic speeds. This greatly enhanced the development of supersonic flight and supersonic aircraft design.
Document 4: List of prolific writers: Some writers have had prolific careers with hundreds of their works being published. While some best-selling authors have written a small number of books that have sold millions of copies, others have had lengthy careers and maintained a high level of output year after year. Dame Agatha Christie, the most-published novelist in history, is estimated to have sold 4 billion books, having written 69 novels and 19 plays. Her works were published between 1920 and 1976, equating to around three publications every two years. Dame Barbara Cartland has also sold millions of copies of her books but wrote many more than Christie. She spent 80 years as a novelist with 722 books published, averaging one book released every 40 days of her career. While Cartland wrote a significant number of full-length novels, other authors have been published many more times but have specialised in short stories. Spanish author Corín Tellado wrote over 5,000 novellas, selling 400 million copies of her books.

The collection contains all of the short stories published in the following collections:
Document 9: Tom Walshaw: Tom D. Walshaw (1912–1998) was an engineer, author and contributor to the British magazine "Model Engineer". Many of his magazine contributions and books were authored under the pseudonym Tubal Cain. The pseudonym relates to the Tubal-cain, the biblical metal worker. As Tubal Cain he made over 424 contributions to "Model Engineer", beginning in 1971. These were mainly divided between workshop equipment articles and model stationary engine constructional articles. He graduated in mechanical engineering at Loughborough University in 1934, and eventually, after a career in mechanical design, went back to that university in 1943, becoming, after some years, senior lecturer in mechanical engineering. He went on in 1948 to teach at University of Liverpool. In 1952 he was appointed Head of Department of Mechanical, Civil and Electrical Engineering at Darlington College of Technology. His final academic post was Head of Mechanical, Production and Civil Engineering at Lancashire Polytechnic. He gained the first of his many model engineering exhibition awards in 1949. At one point he was editor of the "Transactions of the Newcomen Society". Walshaw died on 2 May 1998.

Document 11: Stanley Hart White: Stanley Hart White was a professor of Landscape Architecture at the University of Illinois from 1922 until 1959 and the inventor of the green wall. White called his invention "Botanical Bricks" and developed prototypes in his backyard in Urbana, Illinois. Stanley's brother E.B. White documents the invention in his 1937 letter to Katherine S. White: “I guess everyone has crazy brothers and sisters. I know I have. Stan, by the way, has taken out a patent on an invention of his called ‘Botanical Bricks,’ which are simply plant units capable of being built up to any height, for quick landscape effects, the vertical surfaces covered with flowering vines, or the like. He thinks that the idea has great possibilities for such things as world fairs, city yards, indoor gardens, and many other projects. I think perhaps he has got hold of something, and have written him for more information. He certainly deserves a break.” Stanley refined the vertical garden typology with his patent for the "vegetation-Bearing Architectonic Structure and System (1938)" in which he outlines the scope for a new field of vegetation-bearing architecture. The impact of this invention has still unrealized provocations on this history of gardens and designed landscapes, establishing precedent for verdant modernism in the prewar Middle West. The wall was reconstructed in 2012-13 as part of a Graham Foundation Research Award. Stanley Hart White is also known for his innovative teaching style and his influence on the work of Richard Haag, Hideo Sasaki, Peter Walker, Stu Dawson, Philip H. Lewis Jr., and numerous others Stanley Hart White married Blanche Bigney; they had one daughter, Janice Hart White, an accomplished artist. As E. B. White's niece, Janice was an inspiration for the title character in Stuart Little, Harper and Brothers, 1945.
Document 12: Albert Starr: Albert Starr (born 1926), is a noted American cardiovascular surgeon and pioneer, inventor of the Starr heart valve, who resides and practices in the Portland, Oregon area. Starr is special adviser to OHSU Dean of Medicine Mark Richardson and OHSU President Joseph Robertson (OHSU) at Oregon Health and Science University. Albert Starr was born on June 1, 1926, in New York, New York. He received his B.A. degree from Columbia College (now Columbia University) in 1946 and his M.D. degree from Columbia College of Physicians and Surgeons in 1949. He then went on to do his internship at Johns Hopkins Hospital and his residency in general and thoracic surgery at the Bellevue and Presbyterian Hospitals of Columbia University. He was an assistant in surgeon at Columbia University until 1957, when he moved to Oregon—having been enticed, in part, by the Oregon Heart Association's promises to help fund his research and to take him salmon fishing. There he worked for the Crippled Children's Division at the University of Oregon Medical School (now the Oregon Health and Science University). Starr was an instructor in surgery when he met Lowell Edwards in September 1958. Starr has said of this meeting, "He was in his 60s and I was in my 30s, but there was no generation gap between us.
Document 13: John Alexander Low Waddell: John Alexander Low Waddell (1854 – March 3, 1938, often shortened to J.A.L. Waddell and sometimes known as John Alexander Waddell) was an American civil engineer and prolific bridge designer, with more than a thousand structures to his credit in the United States, Canada, as well as Mexico, Russia, China, Japan, and New Zealand. Waddell’s work set standards for elevated railroad systems and helped develop materials suitable for large span bridges. His most important contribution was the development of the steam-powered high-lift bridge. His design was first used in 1893 for Chicago's South Halsted Street Lift-Bridge over the Chicago River; he went on to design more than 100 other movable bridges, and the company he founded continues to make movable bridges of various types. Waddell was a widely respected writer on bridge design, and an advocate of quality training of engineers. Many of Waddell's surviving bridges are now considered historic landmarks.
