Early Life and Musical Career
Friedrich Wilhelm Herschel was born on 15 November 1738 in Hanover, in the Electorate of Hanover. His father, Isaac Herschel, was a military musician, and William was trained from an early age in music, especially the oboe, violin, and organ. The musical discipline that governed his youth shaped a lifelong habit of practice, craftsmanship, and self-education. As a young man he followed the family profession, and the upheavals of the Seven Years War helped spur his move to Britain, where Hanoverian musicians could find steady work. He anglicized his name to William and spent years performing, composing, and teaching. By the 1760s he had established himself in Bath, an important spa city with a vibrant cultural life. There he served as an organist and musical director, wrote symphonies and concertos, and became a figure of local renown. Music provided not only income but also the stable base from which he would redirect his energies toward science.

Turning to Astronomy
Herschel's curiosity about mathematics and natural philosophy, long pursued in private study, drew him gradually into optics and astronomy. He read treatises on telescope construction and, dissatisfied with commercial instruments, began grinding and polishing his own mirrors. Reflecting telescopes of that era required demanding work with speculum metal, a brittle alloy of copper and tin, and Herschel mastered both the metallurgy and the mechanical fittings. His sister Caroline Herschel joined him in Bath in the 1770s; she trained as a singer under his guidance and soon became indispensable to his scientific routine, maintaining observing logs, timing stellar transits, and later making discoveries in her own right. Their collaboration transformed a household focused on music into one organized for nightly sweeps of the sky.

Discovery of Uranus
On the night of 13 March 1781, while conducting a systematic survey from his garden in New King Street, Bath, Herschel noticed a disk-like object that changed position relative to the fixed stars. At first he suggested it might be a comet, but subsequent observations by himself and others, including the Astronomer Royal, Nevil Maskelyne, showed a near-circular orbit beyond Saturn. The new object was a planet, the first discovered in recorded history since antiquity. Herschel proposed the name Georgium Sidus in honor of King George III; although that label did not prevail internationally, the world came to call the planet Uranus. The discovery brought Herschel to the attention of the scientific community and to the courts of power. With encouragement from figures such as Joseph Banks, then President of the Royal Society, his observations were rapidly communicated, verified, and celebrated. In the same year, he was elected a Fellow of the Royal Society and received its Copley Medal.

Royal Patronage and the Move to Windsor and Slough
The fame of the planetary discovery secured royal patronage. King George III granted Herschel a salary to pursue astronomy full time, and in 1782 he relocated from Bath to Datchet, near Windsor, to be closer to the court. Later he established Observatory House in Slough, where he would live and work for the rest of his life. In Slough he undertook increasingly ambitious projects, culminating in the construction of his immense 40-foot telescope, completed in 1789 with royal support. Though challenging to operate, the instrument symbolized his mastery of large speculum mirrors and his commitment to exploring the faintest reaches of the visible universe.

Caroline Herschel and Collaborative Work
Throughout these years Caroline Herschel was central to the enterprise. She not only recorded and reduced observations but also made her own discoveries, including several comets, and compiled catalogs that enabled efficient surveys. At William's urging, and under the patronage of King George III, Caroline received a salary in 1787 for her scientific assistance, making her one of the first women in Britain to be paid for scientific work. Their organized method of "sweeps" across strips of sky, timed with a sidereal clock and recorded meticulously by Caroline, allowed them to discover and catalog thousands of celestial objects. William's marriage in 1788 to Mary Pitt, a wealthy widow, brought additional stability to the household. Their son, John Herschel, born in 1792, grew up immersed in this working observatory and would later extend his parents' program to the southern skies.

Exploring the Heavens: Nebulae, Double Stars, and the Milky Way
Herschel's telescopes opened a deeper view of the structure of the heavens. He undertook exhaustive surveys of nebulae and star clusters, ultimately assembling catalogs of more than 2, 000 such objects. These catalogs, later expanded by John Herschel and incorporated into broader compilations, guided astronomical work for generations. Herschel recognized that many double stars were not mere alignments but gravitationally bound systems, and he measured changes in their positions over time, helping lay the foundations for stellar astrophysics. He estimated star counts in different directions, a technique he called star-gauging, and from these data reasoned that the Milky Way is a flattened disk-like system with the Sun located away from its center. He also deduced that the Sun itself moves through space toward a point in the constellation Hercules. Seeking to impose order on a sky of bewildering variety, he introduced descriptive categories, including the term "planetary nebula" for round, disk-like gaseous nebulae, and later suggested the word "asteroids" for the small planetary bodies discovered between Mars and Jupiter.

Infrared Radiation and Physical Investigations
Herschel's curiosity extended beyond positional astronomy. In 1800 he explored how sunlight, dispersed by a prism, affected thermometers placed along and beyond the visible spectrum. He found that the greatest heating occurred just beyond the red end, revealing radiation invisible to the eye. He called these "calorific rays", a discovery now recognized as the first detection of infrared radiation. This work demonstrated that the Sun's light was a composite of different rays with distinct physical properties and helped inaugurate the study of radiation beyond visible wavelengths. Herschel also made careful observations of the planets and their satellites, discovered the Uranian moons Titania and Oberon in 1787, and two moons of Saturn, Mimas and Enceladus, in 1789. His reports covered surface markings, atmospheric phenomena, and rotation, always guided by the possibilities afforded by ever-improving optical instruments.

Instruments and Craftsmanship
At the heart of Herschel's achievements stood his telescopes. He and his workshop, with assistance from Caroline and skilled artisans, produced hundreds of mirrors and complete instruments for his own use and for clients across Europe. He refined polishing techniques, invented supports and mountings that allowed smooth "sweeping" of the sky, and experimented with mirror shapes to improve brightness and definition. The giant 40-foot instrument, with a primary mirror of impressive diameter, became a national landmark at Slough. Yet Herschel often preferred more manageable telescopes for routine work, including his 20-foot class reflectors, which offered a balance of aperture and ease of use. His instruments disseminated his methods as much as his publications did, influencing observatories from Britain to the continent.

Recognition, Family, and Later Years
Naturalized as a British subject in 1793, Herschel increasingly became known as Sir William after he was invested in 1816 with the Royal Guelphic Order and knighted. He continued to publish substantial papers in the Philosophical Transactions of the Royal Society and maintained correspondence with astronomers who verified and extended his results. Life at Slough remained a family enterprise. Mary Pitt Herschel managed domestic affairs that sustained the demanding nightly routines; Caroline, though eventually moving to Hanover late in life, preserved and organized records; and John Herschel, growing into his own career, became a principal collaborator during William's later years. Important scientific figures such as Nevil Maskelyne and Joseph Banks intersected his path at crucial moments, helping to formalize recognition of his work and connect it to the broader institutions of science in Britain.

In his final years Herschel reviewed and refined his classifications and reflected on the evolving picture of the cosmos that his instruments had revealed. He died in Slough on 25 August 1822 and was buried nearby. His life traced a path from musician to pioneering astronomer, guided by the same habits of disciplined practice and craftsmanship that had first made him successful in music. Strengthened by the partnership of Caroline Herschel, the support of Mary Pitt, the promise embodied in John Herschel, and the patronage of King George III, he transformed practical telescope making and observational strategy into a new vision of the heavens. The discovery of Uranus and infrared radiation are only the best known of his achievements; equally significant were his systematic surveys, his study of double stars and nebulae, and his efforts to delineate the structure of the Milky Way. Together they established a framework for nineteenth-century astronomy and set a standard for the union of instrument, observation, and theory.
