William Harkness was born on December 17, 1837 in Ecclefechan, Scotland to James Harkness and Jane Wield Harkness. He showed an early aptitude for science and mathematics, which would shape his future career as an astronomer.
Harkness attended Lafayette College in Pennsylvania, where he honed his skills in mathematics and physics. He later pursued further education at the University of Rochester in New York state. It was during this time that he developed a keen interest in astronomy and began to explore the technology behind telescopes.
After completing his studies, Harkness moved to New York City to pursue a career in medicine. However, his plans were interrupted by the outbreak of the Civil War. He enlisted as a Union Army surgeon and served during the war, gaining valuable experience in the field of medicine.
Following the end of the Civil War, Harkness returned to his passion for astronomy. He began designing telescopes and soon gained recognition for his innovative work in the field. In 1874, he was appointed to the Transit of Venus commission, where he played a crucial role in observing and documenting the rare astronomical event.
One of Harkness's most significant contributions to astronomy was the invention of the spherometer caliper, a tool used to measure the curvature of lenses and mirrors in telescopes. This invention revolutionized the way astronomers designed and constructed telescopes, leading to greater precision in their observations.
In 1891, Harkness published his most important scientific work, The Solar Parallax and its Related Constants. This groundbreaking study explored the concept of solar parallax and its implications for the field of astronomy. Harkness's research laid the foundation for future studies on the measurement of celestial distances and the structure of the universe.
William Harkness's contributions to the field of astronomy were widely recognized during his lifetime. In 1899, he was elected president of the American Association for the Advancement of Science, a position he held with great distinction. His work paved the way for future generations of astronomers and scientists to explore the mysteries of the universe.
Harkness's legacy continues to inspire new discoveries in the field of astronomy. His innovative spirit and dedication to scientific inquiry serve as a testament to the power of human curiosity and determination. William Harkness will always be remembered as a pioneer in the study of the cosmos, whose work continues to shape our understanding of the universe.
