Sciences20th Century20th century — the rise of modern astrophysics, the space race, and the popularization of science

Italian astrophysicist born in Florence in 1922, she directed the Astronomical Observatory of Trieste for thirty years. A pioneer of stellar spectroscopy and a gifted science communicator, she made astronomy accessible to the general public.

Frequently asked questions

The key point is that Margherita Hack (1922‑2013) was an Italian astrophysicist who directed the Trieste Observatory for 23 years, becoming the first woman in Italy to lead a major scientific institute. What makes her famous is her dual role: a cutting-edge researcher in stellar spectroscopy and a passionate popularizer capable of explaining star formation to millions of readers. Less known than her science, her commitment to freedom of research and animal rights makes her a complete humanist figure.

Works & Achievements

Spectroscopic Studies on Be and Emission-Line Stars (1960-1980)

A body of landmark scientific publications on B-type emission-line stars, establishing spectroscopic catalogues used by generations of astronomers to classify these distinctive objects with circumstellar envelopes.

L'universo di Margherita Hack (Rizzoli) (1988)

A popular science book that introduced millions of Italians to astronomy, explaining with clarity and enthusiasm the birth of stars, the expansion of the universe, and the latest advances in modern astrophysics.

Dove nascono le stelle (Sperling & Kupfer) (2004)

One of her most widely read popular science books, exploring star formation, black holes, and the origin of the universe. It was adopted in many Italian secondary schools and translated into several languages.

La mia vita in bicicletta (Avverbi) (2007)

An autobiography in which Hack traces her journey as a woman in science in twentieth-century Italy — from athletics to astronomy — offering a testament to her humanist vision and her committed approach to the life of a researcher.

Libera scienza in libero stato (Rizzoli BUR) (2010)

A passionate essay in defence of freedom in scientific research, in which Hack argues for a science free from dogma and ideological interference, placed at the service of truth and human progress.

Direction and Modernisation of the Trieste Observatory (1964-1987)

A major institutional achievement: over 23 years, Hack transformed the OATs into an international research centre, attracted foreign collaborations, and trained several generations of Italian astrophysicists.

Anecdotes

In her youth, Margherita Hack was an accomplished athlete: in 1941, she won the Italian university championships in high jump and long jump in Florence. This drive for self-improvement accompanied her intellectual curiosity throughout her life, reflecting her conviction that mind and body must be equally exercised.

From 1964 to 1987, Margherita Hack directed the Trieste Astronomical Observatory, becoming the first woman in Italy to lead a major scientific research institution. Under her leadership, the observatory earned an international reputation through its cutting-edge work on variable stars and stellar spectroscopy.

A passionate animal lover, Margherita Hack had been vegetarian out of ethical conviction since her youth, and was deeply attached to the many cats she kept. She actively campaigned for animal rights throughout her life, long before such concerns became widely shared in Italian society.

A tireless science communicator, Hack continued to give lectures, write, and appear on television programmes well into old age, making astronomy a passion shared by millions of Italians. She personally replied to thousands of letters from readers, convinced that science belongs to everyone, not just specialists.

In 1994, an asteroid was named ‘8558 Hack’ in her honor by the International Astronomical Union. She would joke that she finally had “a foot in the stars” — she who had devoted her entire career to observing them from Earth.

Primary Sources

Margherita Hack, 'L'universo di Margherita Hack' (Rizzoli) (1988)
Understanding the universe means understanding ourselves, because we are made of the same matter as the stars — we are stardust that has organized itself into increasingly complex forms.
Margherita Hack, 'Dove nascono le stelle' (Sperling & Kupfer) (2004)
Spectroscopy has allowed us to decipher the chemical composition of stars millions of light-years away, a scientific revolution no less important than the invention of the telescope.
Margherita Hack, 'La mia vita in bicicletta' (Avverbi) (2007)
I have pedaled all my life, both literally and figuratively. The bicycle has been my faithful companion, like the stars and my cats.
Margherita Hack, 'Libera scienza in libero stato' (Rizzoli BUR) (2010)
Science cannot progress except in a context of full freedom of thought and research. Any ideological or religious interference in scientific work is a threat to truth.
Hack M., 'Spectroscopic atlas of prototype stars' — spectroscopic studies on Be stars published in Astronomy & Astrophysics (1960s–1970s)
The emission lines observed in the spectra of these stars reveal a circumstellar envelope of ionized gas rotating rapidly around the central star, a phenomenon she was among the first to document systematically.

Key Places

Florence — birthplace and training ground

Born on 12 June 1922 in this city of art and science, Margherita Hack studied at the University there, earning her degree in physics in 1945, within the astronomical tradition inherited from Galileo.

Arcetri Observatory (Florence)

Founded in 1872 on the Arcetri hill where Galileo spent his final years, this observatory was Hack's first research base. There she developed her spectroscopic analysis methods before moving to Trieste.

Trieste Astronomical Observatory (OATs)

Hack served as its director from 1964 to 1987, transforming the institution into an internationally renowned centre specialising in stellar spectroscopy and the astrophysics of hot stars.

University of Trieste

Hack taught astronomy there for decades, training generations of Italian astrophysicists and helping to establish Trieste as a scientific hub recognised across Europe.

Trieste — a life of science and commitment

A cultural crossroads between the Latin and Slavic worlds, Trieste was home to Hack for most of her adult life. She died there on 29 June 2013, leaving a city in mourning that paid her a national tribute.
