Abdus Salam
Abdus Salam (1926–1996) was a Pakistani theoretical physicist whose work helped develop the electroweak theory, a unified description of weak and electromagnetic interactions. He shared the 1979 Nobel Prize in Physics with Sheldon Glashow and Steven Weinberg. Salam also worked to broaden international access to scientific research: he helped establish the International Centre for Theoretical Physics in Trieste, which connected researchers from developing countries with the wider scientific community.

Ada Lovelace
Ada Lovelace (1815–1852) was an English mathematician and writer whose work helped explain the possibilities of Charles Babbage’s proposed Analytical Engine. In 1843 she translated an account of the machine and added extensive notes, including a step-by-step method for calculating Bernoulli numbers. Her writing also explored how a programmable machine might manipulate symbols beyond ordinary arithmetic; the engine itself was never completed.

Emmy Noether
Emmy Noether (1882–1935) was a German mathematician whose work helped shape modern abstract algebra, especially the study of rings and ideals. In mathematical physics, Noether’s theorem connects continuous symmetries of a physical system with conservation laws. Her academic career unfolded amid restrictions on women in German universities: after years of teaching and research without a regular faculty appointment, she was authorized to teach at Göttingen in 1919. The Nazi regime dismissed her in 1933 because she was Jewish. She emigrated to the United States, taught at Bryn Mawr College and lectured at the Institute for Advanced Study, and died in 1935.

Florence Nightingale
Florence Nightingale (1820–1910) was a British nurse, health reformer and statistician. Her work during the Crimean War made her famous, but her longer influence came from campaigning for better hospital sanitation and professional nurse training, and from using data and visual statistics to argue for reform. The popular image of the ‘Lady with the Lamp’ represents only part of her work and the wider institutional changes that shaped wartime medicine.

Hedy Lamarr
Hedy Lamarr (1914–2000) was an Austrian-born American film actor and inventor. With composer George Antheil, she developed and patented a frequency-changing radio system intended to make the control signals for radio-guided torpedoes harder to jam. Her work is recognized as an early contribution to spread-spectrum communications, although it should not be confused with inventing modern Wi-Fi, GPS or Bluetooth systems.

Ibn Battuta
Born in Tangier in 1304, Ibn Battuta was a Moroccan Muslim jurist and traveler whose journeys began with a pilgrimage to Mecca in 1325 and continued for nearly three decades. His travel narrative, commonly called the Rihla, was dictated to the writer Ibn Juzayy around 1353 and describes journeys across much of Africa and Eurasia. The account is an important source for the history of the 14th-century Muslim world, though some dates and reported episodes remain uncertain.

John Snow (physician)
John Snow (1813–1858) was an English physician whose work influenced both anesthesiology and epidemiology. He helped make ether and chloroform administration more controlled and argued that cholera spread through contaminated water. His analyses of London's water supplies and his investigation of the 1854 Soho outbreak became influential examples of evidence-led public health, though his theory met resistance during his lifetime and the Broad Street pump-handle episode alone did not account for the outbreak's decline.

Lise Meitner (1878–1968) was an Austrian-born physicist whose research on radioactivity and nuclear physics helped explain nuclear fission. After fleeing Nazi Germany in 1938, she continued working in Sweden and, with her nephew Otto Frisch, interpreted evidence that uranium nuclei could split after neutron bombardment. The 1944 Nobel Prize in Chemistry was awarded to her longtime collaborator Otto Hahn alone, although historical accounts have debated how credit for the discovery should be shared.

Socrates
Socrates (c. 470–399 BCE) was an Athenian philosopher whose practice of questioning people about ethics and knowledge became a model for later philosophy. He left no writings of his own, so accounts of his life and ideas come chiefly from Plato, Xenophon and Aristophanes and do not always agree. Tried and sentenced to death in Athens in 399 BCE, Socrates became a central figure in the history of Western philosophy.

William Shakespeare
William Shakespeare (1564–1616) was an English playwright, poet and actor whose career connected Stratford-upon-Avon with London's professional theatre. By 1592 he was established in London, and he later became a member and shareholder of the Lord Chamberlain's Men, renamed the King's Men in 1603. His plays and poems were printed during his lifetime, while colleagues published the First Folio in 1623, preserving many plays that had not previously appeared in print.
