[2][3][4][5][6][7] With her husband William Huggins she was a pioneer in the field of spectroscopy and co-wrote the Atlas of Representative Stellar Spectra (1897).

Margaret's early education took place privately at her home in Dublin, where she studied art, classics, literature, languages and music.

[11] The exact location is unknown, but during this time period Brighton had at least two private boarding schools for girls, both now defunct.

[12] Margaret also developed a keen interest in photography, which she studied in her spare time; something which would later play a role in her career.

[14] Evidence suggests that Margaret was instrumental in instigating William Huggins' successful program in photographic research.

The London Times, in the notice of the death of Huggins, mentioned that Richard Proctor referred to her as the "Herschel of the Spectroscope".

[citation needed][16] After their marriage on 8 September 1875, at the Monkstown Parish Church, the "two star-gazed"[17] lovers devoted themselves to their research and their inspiring companionship resulted in an array of astronomical findings.

Margaret and William Huggins were the first to "observe and to identify the series of hydrogen lines in the spectrum of the star Vega.

"[12] The pair's detailed notebook entries contributed to their first paper publication in 1889, discussing the "studies of the spectra of planets".

In 1903, Margaret and William Huggins published their final piece of joint scientific research on the spectra of certain radioactive substances.

In 1875, Margaret and her husband William began photographic experiments, which were meticulously documented in observatory notebooks.

Aware of her illness, she decided to donate her scientific and artistic treasures to Wellesley College in the United States.
