Alexander Rich: Alexander Rich (November 15, 1924 – April 27, 2015) was an American biologist and biophysicist.  He was the William Thompson Sedgwick Professor of Biophysics at MIT (since 1958) and Harvard Medical School.  Dr. Rich earned both an A.B. ("magna cum laude") and an M.D. ("cum laude") from Harvard University.  He was a post-doc of Linus Pauling along with James Watson.

The 20 Greatest Christmas Songs: The 20 Greatest Christmas Songs is a compilation/remix album by Boney M..  In 1986 producer Frank Farian took the master tapes from 1981's "Christmas Album", added six recordings by Liz Mitchell, Reggie Tsiboe and two session singers from 1984, remixed them and created "Die 20 schönsten Weihnachtslieder der Welt", internationally released as "The 20 Greatest Christmas Songs".  The 1986 version of the Boney M. Christmas album has since been re-issued as "The Most Beautiful Christmas Songs of the World" (1992), "A Wonderful Christmas Time" (1998) and "Christmas Party" (1998 and 2003).

Raúl Cuero: Raúl Gonzalo Cuero Rengifo (born in Buenaventura, Colombia) is an African Colombian professor of microbiology.  From 1988 through 2012 he was a professor at Prairie View A&M University researching biological resistance to ultraviolet light.  The work was supported in part by NASA and led to at least one publication and patent.  During this period, Colombian media portrayed Cuero as "one of the greatest scientists in the world" who was internationally acknowledged as one of the greatest Colombian inventors, stated he had over 100 publications in scientific journals, and claimed he had won a significant award from NASA.  Since 2012, he has been the research director of International Park of Creativity, an organization of which he is the founder.

Ken Caldeira: In the 1980s, Caldeira worked as a software developer.  He received his Ph.D in Atmospheric Sciences in 1991 from the New York University Department of Applied Science.  From 1991 to 1993, Caldeira worked at Penn State University as a post-doctoral researcher.  He then worked as an Environmental Scientist and Physicist at Lawrence Livermore National Laboratory until 2005, when he began his current position at the Carnegie Institution: Department of Global Ecology.  He was named a "Hero Scientist of 2008" by "New Scientist" magazine and listed as number 36 out of 100 "Agents of Change" in "Rolling Stone" magazine's 2 April 2009 list of 100 "artists and leaders, policymakers, writers, thinkers, scientists and provocateurs who are fighting every day to show us what is possible."  Bill Gates, in his 2016 end-of-year blog post, referred to Ken Caldeira as “my amazing teacher”.

On Giants' Shoulders: On Giants' Shoulders was written in 1998 by Melvyn Bragg.  The book was assembled after a series of interviews Bragg had with current scientists about the world's greatest scientists such as Archimedes, Isaac Newton and Einstein.  Bragg, who brands himself as a "non-scientist", conducted these interviews on BBC Radio 4 for other non-scientists.  The book looks at the notion of being a "genius" and through discussions with 20th-century scientists explores the extent to which the great scientists of history were geniuses.

John Aubrey: John Aubrey FRS ( ; 12 March 1626 – 7 June 1697), was an English antiquary, natural philosopher and writer.  He is perhaps best known as the author of the "Brief Lives", his collection of short biographical pieces.  He was a pioneer archaeologist, who recorded (often for the first time) numerous megalithic and other field monuments in southern England, and who is particularly noted as the discoverer of the Avebury henge monument.  The Aubrey holes at Stonehenge are named after him, although there is considerable doubt as to whether the holes that he observed are those that currently bear the name.  He was also a pioneer folklorist, collecting together a miscellany of material on customs, traditions and beliefs under the title "Remaines of Gentilisme and Judaisme".  He set out to compile county histories of both Wiltshire and Surrey, although both projects remained unfinished.  His "Interpretation of Villare Anglicanum" (also unfinished) was the first attempt to compile a full-length study of English place-names.  He had wider interests in applied mathematics and astronomy, and was friendly with many of the greatest scientists of the day.

Jack W. Szostak: Jack William Szostak (born November 9, 1952) is a Canadian American biologist of Polish British descent, Nobel Prize laureate, Professor of Genetics at Harvard Medical School and Alexander Rich Distinguished Investigator at Massachusetts General Hospital, Boston.  Szostak has made significant contributions to the field of genetics.  His achievement helped scientists to map the location of genes in mammals and to develop techniques for manipulating genes.  His research findings in this area are also instrumental to the Human Genome Project.  He was awarded the 2009 Nobel Prize for Physiology or Medicine, along with Elizabeth Blackburn and Carol W. Greider, for the discovery of how chromosomes are protected by telomeres.

George Mercer Dawson: George Mercer Dawson, {'1': ", '2': ", '3': ", '4': "} , (August 1, 1849 – March 2, 1901) was a Canadian geologist and surveyor.  He was born in Pictou, Nova Scotia, the eldest son of Sir John William Dawson, Principal of McGill University and a noted geologist, and his wife, Lady Margaret Dawson.  By age 11, he was afflicted with tuberculosis of the spine (Pott's disease) that resulted in a deformed back and stunted growth.  Physical limitations, however, did not deter Dawson from becoming one of Canada's greatest scientists.

Linus Pauling: Linus Carl Pauling (February 28, 1901 – August 19, 1994) was an American chemist, biochemist, peace activist, author, and educator.  He published more than 1,200 papers and books, of which about 850 dealt with scientific topics. " New Scientist" called him one of the 20 greatest scientists of all time, and as of 2000, he was rated the 16th most important scientist in history.

20 Greatest Hits (Beatles album): 20 Greatest Hits is a compilation album featuring a selection of songs by The Beatles that were number one singles in the UK and US.
