A pioneering astronomer who discovered numerous variable stars and contributed significantly to the field of astronomy, particularly in the study of celestial bodies' brightness changes.
Janet Akyz Mattei, a Turkish-American astronomer, left an indelible mark on the world of astronomy, dedicating over three decades of her life to the American Association of Variable Star Observers (AAVSO) as its director from 1973 to 2004. Her remarkable tenure was marked by an unparalleled passion for collecting observations of variable stars, fostering collaboration between amateur astronomers and professionals, and inspiring generations of students and educators alike.
Born on January 2, 1943, in Bodrum, Turkey, to Turkish-Jewish parents, Bella and Baruh Akyz, Janet's curiosity about the universe began at a young age. She pursued her higher education at Brandeis University in Waltham, Massachusetts, on the Wien Scholarship, where her fascination with astronomy grew exponentially.
Janet's academic achievements were matched only by her professional pursuits. She worked at the Leander McCormick Observatory in Charlottesville, Virginia, from 1970 to 1972, earning her M.A. in Astronomy from the University of Virginia in 1972. Her Ph.D. in Astronomy from Ege University in Izmir, Turkey, in 1982, solidified her reputation as a leading expert in her field.
As the driving force behind AAVSO, Janet revolutionized the way variable star observations were collected, analyzed, and shared. Her vision enabled amateur astronomers to contribute significantly to our understanding of the cosmos, while fostering lasting partnerships with professional astronomers.
Under her leadership, the AAVSO database was made accessible to educators, empowering students and researchers worldwide. Janet's tireless efforts also facilitated non-professional astronomers' access to the Hubble Space Telescope, democratizing the pursuit of astronomical knowledge.
Asteroid 11695 Mattei, named in her honor on January 9, 2001, serves as a celestial testament to her remarkable contributions.
Janet's untimely passing on March 22, 2004, at the age of 61, due to leukemia, was a shock to the astronomical community. Yet, her unwavering dedication and passion for astronomy continue to inspire new generations of scientists, educators, and enthusiasts.
As we gaze up at the stars, we remember Janet Akyz Mattei, a shining star in her own right, whose work continues to illuminate our understanding of the universe and our place within it.
Born in 1885
Measured the galaxy's size and mapped the Milky Way's structure, revolutionizing our understanding of the universe.
Born in 1900
Pioneering astronomer who discovered that stars are primarily composed of hydrogen and helium, revolutionizing our understanding of the universe. Her groundbreaking work paved the way for future generations of astronomers.
Born in 1863
Pioneering astronomer who classified over 350,000 stars and developed a system of stellar classification still used today. Her work paved the way for future astronomers to better understand the universe.
Born in 1818
Pioneering astronomer and academic who discovered a comet and was the first woman elected to the American Academy of Arts and Sciences, paving the way for future generations of women in science.
Born in 1750
First female astronomer to receive a salary, discovered several comets and double stars, and assisted her brother William in his astronomical observations.
Born in 1857
A pioneering female astronomer who cataloged thousands of stars, discovered 59 gaseous nebulae, and developed a system for classifying stars based on their spectra. Her work laid the foundation for modern astrophysics.
Born in 1873
Developed the Hertzsprung-Russell diagram, a fundamental tool in astronomy that relates stars' brightness to their color and temperature. This diagram revolutionized our understanding of stars and their life cycles.
