Explore the story of Cecilia Payne, whose discovery reshaped our understanding of the universe—and what it teaches us about perseverance, recognition, and excellence.



In Episode 227 of Anecdotally Speaking, Mark shares the inspiring story of Cecilia Payne, a pioneering astronomer who, despite her groundbreaking discovery about the composition of the sun, didn’t receive the recognition she deserved—at least, not right away.

Mark and Shawn discuss the powerful themes of perseverance, hidden brilliance, and the importance of recognition. In a world that often overlooks true innovators, Cecilia Payne’s story serves as a reminder to strive for excellence, even when acknowledgment is elusive.

In a business context, this story illustrates the significance of “being too good to ignore,” following your passion, and remaining open to new ideas. This episode encourages us to give due credit and honour those who shape the world in ways we may not immediately see.

Cecilia Payne was born in England in 1900 and overcame numerous barriers to pursue her love for science. Coming from a modest background and receiving little support from her family, she excelled in physics and chemistry, eventually earning a scholarship to Cambridge University in 1919. Her fascination with astronomy took root after attending a lecture by Arthur Eddington, an astronomer who had gone to Africa to test Einstein’s theory of relativity during a solar eclipse. Inspired, Payne resolved to make astronomy her life’s work.

After completing her studies at Cambridge, Payne faced the reality that the university did not award degrees to women. Determined to continue her scientific journey, she moved to the United States, where she joined the Harvard College Observatory. Encouraged by her mentor, Harlow Shapley, she began a dissertation that would challenge conventional thinking.

At the time, scientists believed that the sun and Earth shared a similar chemical composition. Through her research, Payne discovered this was not the case. She showed that while the heavier elements were present in both the Earth and the sun, hydrogen dominated the sun’s composition—by a factor of a million compared to Earth. This insight revealed a fundamental truth: the universe was mostly made up of hydrogen, a fact that would change humanity’s understanding of the cosmos.

However, despite the importance of her discovery, her findings faced scepticism. Her PhD examiner, the astronomer Henry Russell, discouraged her from asserting her conclusions about hydrogen’s abundance, dismissing her results as “spurious.” Only years later did Russell realize Payne was correct. He published a paper supporting the same conclusions, offering a brief nod to Payne’s work. Russell gained widespread recognition, while Payne’s contribution went largely unacknowledged at the time.

Despite this, Payne persevered and eventually built a respected career. She stayed at Harvard, becoming one of the first female professors and later the head of the department. Her work, particularly on variable stars, advanced the field of astronomy. Today, her findings on the makeup of the sun and stars remain fundamental to the field, and her calculations about hydrogen and helium are still used.
