Hertha Ayrton
A pioneering engineer and inventor who mastered the electric arc, defended women's intellectual rights, and fought fiercely for suffrage.
1854–1923 (age 69)·English electrical engineer and activist·Birthday: April 28
Biography
Hertha Ayrton battled prejudice with precision and passion. Born Phoebe Sarah Marks in Victorian England, she financed her own education at Cambridge through teaching and needlework, though as a woman she was denied a degree. Undeterred, she turned her brilliant, practical mind to electrical engineering. Her groundbreaking work on the hissing, unstable electric arc light—a major source of public lighting—led to a series of patents and a definitive treatise that transformed the field. In 1906, the Royal Society awarded her the Hughes Medal for this research, a monumental recognition, though they still barred her from fellowship. Ayrton was equally formidable as an activist. A committed suffragette, she sheltered fugitives, marched in protests, and applied her inventiveness to creating a device for dispersing poison gas in the trenches during WWI. Her life was a constant demonstration that intellectual rigor and social justice were inseparable pursuits.

Did You Know?
Her first name, Hertha, was chosen from a Swinburne poem by her friend Ottilie Blind.
She married physicist William Edward Ayrton, a supporter of women's education in science.
She invented the 'Ayrton fan' used in the trenches of WWI to dispel poison gas.
She was the first woman to read her own paper before the Institution of Electrical Engineers.
“An error that ascribes to a man what was actually the work of a woman has more lives than a cat.”
