1. Rosalind Franklin (1920–1958)Field: Molecular Biology and X-ray Crystallography Rosalind Franklin’s precise X-ray diffraction images of DNA, particularly the famous Photograph 51, provided critical evidence that DNA has a double-helix structure. Her data were shown without her permission to James Watson and Francis Crick, who used the information to build their model of DNA in 1953. Watson, Crick, and Maurice Wilkins received the 1962 Nobel Prize in Physiology or Medicine; Franklin, who had died four years earlier, was not recognized. Her case remains one of the most cited examples of gender bias in twentieth-century science, highlighting how access to data…

1. Fortran (1957)Fortran, developed by IBM through John Backus's direction, became the earliest high-level programming language to achieve widespread adoption. Engineered for technical and scientific computations, this innovation shifted coding practices away from tedious machine instructions toward comprehensible mathematical expressions. Initial performance evaluations demonstrated that Fortran-based programs executed with a speed comparable to manual assembly code, successfully driving swift industrial acceptance.For decades, Fortran dominated scientific computing, weather modeling, nuclear simulations, and aerospace engineering. Even today, critical systems in physics and climate science rely on modern Fortran standards. Its introduction of the compiler as a practical tool and its emphasis on…
