Photojournalist Gerda Taro was the first female war photographer to be killed covering the front lines of combat. Her work documenting the Spanish Civil War fundamentally altered the standards of modern war photojournalism. Born #OTD in 1910. Her legacy was largely erased by history until... 1/2🧵

A compelling black-and-white portrait of pioneering war photojournalist Gerda Taro (1910–1937), renowned for her courageous frontline documentation of the Spanish Civil War and her tragic history as the first female combat photographer killed in action. Photographed from a slightly high angle, Taro sits looking directly up at the camera with a bright, engaged expression, a gentle smile, and wide, expressive dark eyes framed by perfectly arched eyebrows. Her dark hair is styled back in soft, elegant waves. She wears a heavy, texturized fur or faux-fur coat with prominent lapels over a dark, knit, cross-hatched sweater and a crisp white collared shirt peek-a-booed underneath. Her hands rest naturally on a vintage, mechanical portable typewriter sitting open before her, highlighting her dual role in journalism. The composition features a shallow depth of field, rendering the dimly lit room behind her softly out of focus, evoking an intimate, intensely intellectual, and historically significant mood.

Helen Sawyer Hogg: one of the most prominent & celebrated astronomers of the 20th century. She revolutionized our understanding of the universe through her foundational research on globular clusters--massive, spherical groupings of closely packed stars orbiting the core of our galaxy. #WomenInSTEM🧵

A striking profile portrait of renowned astronomer Helen Sawyer Hogg (1905–1993) standing before the David Dunlap Observatory dome, symbolizing her pioneering decades mapping globular clusters and variable stars. Photographed from a slightly low angle, the older, white-haired scientist gazes upward and to the left with a serene, proud expression, her face warmly illuminated by natural sunlight. She wears glasses with tortoiseshell arms, a simple headband, a structured pinkish-gray tweed jacket, a delicate gold necklace, and a round gold brooch on her collar. The soft-focus background highlights the white architectural dome of the observatory contrasted against a deep blue sky and dark green trees, emphasizing her lifework in observational astrophysics. The composition balances her dignified human presence with the monumental scientific structure behind her, evoking a hopeful, reflective mood that honors her historical significance as a barrier-breaking female leader in 20th-century global science.

Chemist Stephanie Kwolek invented Kevlar in 1965. In a 40+ year career, her work in polymer chemistry ultimately revolutionized personal body armor, industrial engineering & space exploration. Fourth woman inducted, National Inventors Hall of Fame, 1994. She was born #OTD in 1923. #WomenInSTEM

Fun color photograph of pioneering American chemist Stephanie Kwolek (1923–2014), the inventor of Kevlar, taken in her later years. She is indoors in what appears to be a home or lab setting with soft lighting and kitchen-like background elements. Kwolek, an older woman with short gray hair, wears large round eyeglasses, a light plaid blouse or dress with a white collar, and holds up a bright yellow circular button that reads "ASK ME ABOUT KEVLAR" in bold black lettering. On her hand she wears thick yellow Kevlar protective gloves (the very material she invented), one glove prominently displayed in the foreground as she grips the button. Her expression is gentle, proud, and welcoming, with a slight smile, embodying her lifelong dedication to science, safety, and innovation as she invites conversation about her groundbreaking discovery that revolutionized bullet-resistant vests, tires, helmets, and countless other applications.

What a great photo. Now that's a vibe. Maybe every year instead of "resolutions" (I don't usually make resolutions anyway) I should print a photo of a woman from history from whom I want to capture a bit of her ineffable spirit. Maybe next year is Year of Oceanographic Cartographer Marie Tharp.
