LADY STARDUST Margaret Burbidge, who celebrates her 100th birthday in August, had a long and stellar career in multiple fields of astrophysics. One of her most significant achievements was formulating our understand- ing of nucleosynthesis in stars. Among positions she held in her lifetime were director of the Royal Greenwich Observatory and president of the American Astronomical Society, both the first time that a woman filled the post.

The years immediately following World War II would turn out to be career-defining for the young astronomer. Along- side giving classes on practical astronomy on the observatory roof — to students that included an enthusiastic undergradu- ate named Arthur C. Clarke — she also attended graduate lectures in physics. There, she immediately hit it off with “an interesting person” called Geoffrey (Geoff) Burbidge who she would go on to marry just six months later. From the outside, the pair made an unlikely couple. Geoff was a large man with a truculent, impatient character, while Margaret was so demure and quiet that Miller claims, “My tronomy at the time, and she 1983 tendered her resignation just a B2FH was a transformative year and a half later. paper deserving of the highest accolades.
