From the October 1927 Fifth Solvay International Conference on Electrons and Photons
On the shoulders of giants.
Back row: Auguste Piccard, Émile Henriot, Paul Ehrenfest, Édouard Herzen, Théophile de Donder, Erwin Schrödinger, Jules-Émile Verschaffelt, Wolfgang Pauli, Werner Heisenberg, Ralph Howard Fowler, Léon Brillouin.
Middle row: Peter Debye, Martin Knudsen, William Lawrence Bragg, Hendrik Anthony Kramers, Paul Dirac, Arthur Compton, Louis de Broglie, Max Born, Niels Bohr.
Front row (seated): Irving Langmuir, Max Planck, Marie Skłodowska Curie, Hendrik Lorentz, Albert Einstein, Paul Langevin, Charles-Eugène Guye, Charles Thomson Rees Wilson, Owen Willans Richardson.
Hendrik Lorentz, Leiden University, seated between Madame Curie and Einstein, chaired the conference. A few months later he became seriously ill, and died 4th February 1928.
Among the 29 scientists that attended the conference are 17 that were or became Nobel Price winners, none more so than Marie Sklodowska Curie that at this time held two Nobel Prices, one in physics (shared with her husband Pierre Curie and with Henri Becquerel, 1903) the other for chemistry (she was sole winner, 1911).
Marie Curies love affair (after her husband Pierre Curie died 1906) with Paul Langevin (seated next to Einstein in this picture), developed into a major scandal in France during 1911, and had some consequences for her Nobel Price in chemistry that year. She had to write the Swedish Academy and point out that she was awarded the price for her scientific work, and not for her private life, before she officially was declared the winner of chemistry that year.
Werner Heisenberg & Niels Bohr, and their Copenhagen meeting during WW.II (1941), are the basis for Michael Frayn's play Copenhagen, about scientists and their responsibilities.
