Alexander Graham Bell (March 3, 1847 – August 2, 1922) was an eminent scientist, inventor, engineer and innovator who is credited with inventing the first practical telephone. Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work.
John Napier of Merchistoun (1550 – 4 April 1617) – also signed as Neper, Nepair – named Marvellous Merchiston, was a Scottish mathematician, physicist, astronomer & astrologer, and also the 8th Laird of Merchistoun. He was the son of Sir Archibald Napier of Merchiston. John Napier is most renowned as the inventor of the logarithm, and of an invention called "Napier's bones". Napier also made common the use of the decimal point in arithmetic and mathematics.
James Clerk Maxwell (13 June 1831 – 5 November 1879) was a Scottish theoretical physicist and mathematician. His most important achievement was classical electromagnetic theory, synthesizing all previously unrelated observations, experiments and equations of electricity, magnetism and even optics into a consistent theory.
James Watt, FRS, FRSE (19 January 1736 – 25 August 1819) was a Scottish inventor and mechanical engineer whose improvements to the Newcomen steam engine were fundamental to the changes brought by the Industrial Revolution in both the Kingdom of Great Britain and the world.
John James Rickard Macleod (6 September 1876 – 16 March 1935) was a Scottish physician and physiologist. He was noted as one of the co-discoverers of insulin and given the Nobel Medal for this discovery.
William Kennedy Laurie Dickson (3 August 1860 – 28 September 1935) was a French-Anglo-Scottish inventor who devised an early motion picture camera under the employ of Thomas Edison (post-dating the work of Louis Le Prince).
William Thomson, 1st Baron Kelvin (or Lord Kelvin), OM, GCVO, PC, PRS, PRSE, (26 June 1824 – 17 December 1907) was a Belfast-born mathematical physicist and engineer. At the University of Glasgow he did important work in the mathematical analysis of electricity and formulation of the first and second Laws of Thermodynamics, and did much to unify the emerging discipline of physics in its modern form.
Sir Robert Alexander Watson-Watt, KCB, FRS, FRAeS (13 April 1892 – 5 December 1973) is considered by many to be the "inventor of radar". (The hyphenated name is used herein for consistency, although this was not adopted until he was knighted in 1942.
John Logie Baird (14 August 1888 – 14 June 1946) was a Scottish engineer and inventor of the world's first working television system, also the world's first fully electronic colour television broadcast. Although Baird's electromechanical system was eventually displaced by purely electronic systems, his early successes demonstrating working television broadcasts and his colour and cinema television work earn him a prominent place in television's invention.
Sir James Dewar FRS (20 September 1842 – 27 March 1923) was a British chemist and physicist. He is probably best-known today for his invention of the Dewar flask, which he used in conjunction with extensive research into the liquefaction of gases. He was also particularly interested in atomic and molecular spectroscopy, working in these fields for more than 25 years.
William Murdoch (sometimes spelled Murdock) (21 August 1754 – 15 November 1839) was a Scottish engineer and inventor. It is believed he Anglicised his name to Murdock when he moved to England. Murdoch was employed by the firm of Boulton and Watt and worked for them in Cornwall as a steam engine erector for ten years, spending most of the rest of his life in Birmingham. He was the inventor of gas lighting in the early 1790s and coined the term gasometer.
Henry Charles Fleeming Jenkin (25 March 1833 – 12 June 1885) was Professor of Engineering at the University of Edinburgh, remarkable for his versatility. Known to the world as the inventor of telpherage, he was an electrician and cable engineer, a lecturer, linguist, critic, actor, dramatist and artist. His descendants include the Tory MPs Patrick, Lord Jenkin of Roding and Bernard Jenkin.
James Hall Nasmyth (sometimes spelled Naesmyth, Nasmith, or Nesmyth) (August 19, 1808 – May 7, 1890) was a Scottish engineer and inventor famous for his development of the steam hammer. He was the co-founder of Nasmyth, Gaskell and Company manufacturers of machine tools. He retired at the age of 48, and moved to Penshurst, Kent where he developed his hobbies of astronomy and photography.
John Loudon McAdam (September 21, 1756 – November 26, 1836) was a Scottish engineer and road-builder. He invented a new process, "macadamisation", for building roads with a smooth hard surface that would be more durable and less muddy than soil-based tracks. Modern road construction still reflects McAdam's influence.
James Gregory FRS (November 1638 – October 1675) was a Scottish mathematician and astronomer. He described the first practical reflecting telescope - the Gregorian telescope - and made advances in trigonometry, discovering infinite series representations for several trigonometry functions.
Lieutenant-General Sir William Boog Leishman (November 6, 1865 - June 2, 1926) was a Scottish pathologist and British Army medical officer. He was Director-General of Army Medical Services from 1923 to 1926. He was born in Glasgow and attended Westminster School and the University of Glasgow and entered the Royal Army Medical Corps. He served in India, where he studied enteric fever and kala azar. He returned to the United Kingdom and was stationed at the Victoria Hospital in Netley in 1897.
James David Forbes FRS (20 April 1809 – 31 December 1868) was a Scottish physicist who worked extensively on the conduction of heat, seismology and glaciology. Forbes was a resident of Edinburgh for most of his life, educated at the University and a professor there from 1833 until he became principal of the United College of St. Andrews in 1859.
Sir James Whyte Black, OM, FRS, FRSE, FRCP (born 14 June 1924) is a Scottish doctor and pharmacologist who invented Propranolol, synthesized Cimetidine and was awarded the Nobel Prize for Medicine in 1988 for these discoveries.
