James Robert Wallace, Baron Wallace of Tankerness, (born 25 August 1954) is a Scottish politician serving as a Liberal Democrat life peer in the British House of Lords since 2007 and Moderator of the General Assembly of the Church of Scotland from 2021 to 2022. He served as the Deputy First Minister of Scotland from 1999 to 2005, and during that time he served twice as acting First Minister, in 2000, in the aftermath of Donald Dewar's death and in 2001, following Henry McLeish's resignation. He was formerly Leader of the Scottish Liberal Democrats from 1992 to 2005 and Liberal Democrats in the House of Lords from 2013 to 2016.
Wallace served as a Liberal Democrat Member of Parliament (MP) for Orkney and Shetland from 1983 to 2001 and a Member of the Scottish Parliament (MSP) for Orkney from 1999 to 2007. He also served as Advocate General for Scotland from 2010 to 2015. He was the Moderator of the General Assembly of the Church of Scotland from 1 May 2021 to 23 May 2022.

Linus Carl Pauling ( PAW-ling; February 28, 1901 – August 19, 1994) was an American chemist, biochemist, chemical engineer, 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. For his scientific work, Pauling was awarded the Nobel Prize in Chemistry in 1954. For his peace activism, he was awarded the Nobel Peace Prize in 1962. He is one of five people to have won more than one Nobel Prize (the others being Marie Curie, John Bardeen, Frederick Sanger, and Karl Barry Sharpless). Of these, he is the only person to have been awarded two unshared Nobel Prizes, and one of two people to be awarded Nobel Prizes in different fields, the other being Marie Curie.Pauling was one of the founders of the fields of quantum chemistry and molecular biology. His contributions to the theory of the chemical bond include the concept of orbital hybridisation and the first accurate scale of electronegativities of the elements. Pauling also worked on the structures of biological molecules, and showed the importance of the alpha helix and beta sheet in protein secondary structure. Pauling's approach combined methods and results from X-ray crystallography, molecular model building, and quantum chemistry. His discoveries inspired the work of Rosalind Franklin, James Watson, Francis Crick, and Maurice Wilkins on the structure of DNA, which in turn made it possible for geneticists to crack the DNA code of all organisms.In his later years, he promoted nuclear disarmament, as well as orthomolecular medicine, megavitamin therapy, and dietary supplements, especially ascorbic acid (commonly known as Vitamin C). None of his ideas concerning the medical usefulness of large doses of vitamins have gained much acceptance in the mainstream scientific community. He was married to the American human rights activist Ava Helen Pauling.

John Boyd Orr, 1st Baron Boyd-Orr, (23 September 1880 – 25 June 1971), styled Sir John Boyd Orr from 1935 to 1949, was a Scottish teacher, medical doctor, biologist, nutritional physiologist, politician, businessman and farmer who was awarded the Nobel Peace Prize for his scientific research into nutrition and his work as the first Director-General of the United Nations Food and Agriculture Organization (FAO).
He was the co-founder and the first President (1960–1971) of the World Academy of Art and Science (WAAS). In 1945, he was elected President of the National Peace Council and was President of the World Union of Peace Organisations and the World Movement for World Federal Government.

Hendrik Antoon Lorentz (; 18 July 1853 – 4 February 1928) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Pieter Zeeman for the discovery and theoretical explanation of the Zeeman effect. He derived the Lorentz transformation of the special theory of relativity, as well as the Lorentz force, which describes the combined electric and magnetic forces acting on a charged particle in an electromagnetic field. Lorentz was also responsible for the Lorentz oscillator model, a classical model used to describe the anomalous dispersion observed in dielectric materials when the driving frequency of the electric field was near the resonant frequency, resulting in abnormal refractive indices.
According to the biography published by the Nobel Foundation, "It may well be said that Lorentz was regarded by all theoretical physicists as the world's leading spirit, who completed what was left unfinished by his predecessors and prepared the ground for the fruitful reception of the new ideas based on the quantum theory." He received many other honours and distinctions, including a term as chairman of the International Committee on Intellectual Cooperation, the forerunner of UNESCO, between 1925 and 1928.

Group Captain James Martin Stagg, (30 June 1900 – 23 June 1975) was a British Met Office meteorologist attached to the Royal Air Force during the Second World War who notably persuaded General Dwight D. Eisenhower to change the date of the Allied invasion of Europe from 5 to 6 June 1944.

Marion Amelia Spence Ross FRSE (9 April 1903 – 3 January 1994) was a Scottish physicist noted for her work in x-ray crystallography and fluid dynamics.

José Luis Torero (born in Lima, Peru) is a professor in fire protection engineering. He is currently the head of the Department of Civil, Environmental and Geomatic Engineering at University College London (UK). He took this appointment after two years (2017-2019) as the John L. Bryan Chair in the Department of Fire Protection Engineering and Director of the Center for Disaster Resilience in the Department of Civil and Environmental Engineering at the University of Maryland (USA). He was formerly the Head of the School of Civil Engineering at the University of Queensland (2012-2017). He is Fellow of the Royal Academy of Engineering (UK) since 2010, the Australian Academy of Technological Sciences and Engineering since 2014 and The Royal Society of Edinburgh (UK) since 2008. He held the BRE/RAE Chair in Fire Safety Engineering and directed the BRE Centre for Fire Safety Engineering from 2004 to 2012. In 2018 he was elected a Fellow of the Royal Society of New South Wales, being gazetted in the NSW Government Gazette (No 8, Thursday 31 January 2019) by the then Governor of New South Wales (now Governor General of Australia) His Excellency General, the Honourable David Hurley AC DSC(Rtd).He was co-chair of Fire Safety at the Council on Tall Buildings and Urban Habitat from 2009 to 2015.
He was the Editor-in-Chief of Fire Safety Journal (2010 - 2016) and a member of the editorial board member of numerous journals including Fire Technology, and Progress in Energy and Combustion Science.

Sir James Walker FRS FRSE FCS LLD (6 April 1863 – 6 May 1935) was a Scottish chemist.

Sir David Percival Dalbreck Wilkie, (5 November 1882 – 28 August 1938), known to friends and colleagues as DPD, was among the first of the new breed of professors of surgery appointed at a relatively young age to develop surgical research and undergraduate teaching. At the University of Edinburgh, he established a surgical research laboratory from which was to emerge a cohort of young surgical researchers destined to become the largest dynasty of surgical professors yet seen in the British Isles. He is widely regarded as the father of British academic surgery.

Dr Walter Michel Levinthal FRSE (1886–1963) was a German-born bacteriologist, working in Britain in the 20th century. He gave his name to Levinthal's Agar. He is known for his work on Psittacosis and the influenza virus.
