Benjamin Franklin is credited with discovering electricity in 1752
Franklin's experiment with a kite and wire in a thunderstorm demonstrated that lightning consists of electricity. This discovery was a significant milestone in the history of electricity and paved the way for further exploration and innovation.
Franklin's work in electricity was preceded by scientists such as William Gilbert, who in 1600, published the first theories about electricity in his book, "De Magnete". In this book, Gilbert coined the term "electricus", which was later modified to "electricity" by polymath Sir Thomas Browne in 1646. German scientist Otto von Guericke successfully produced static electricity through his experiments, and Stephen Gray discovered the difference between electrical insulators and conductors, finding that electricity could flow along wires.
Following Franklin's discovery, many other scientists continued to study electricity and made significant contributions. Thomas Edison, for example, patented the electric lightbulb in 1879, and established the world's first electric power distribution system. Michael Faraday invented the electric motor in 1821 and formulated laws of electromagnetic induction, demonstrating the generation of electricity through moving magnetic fields.
The discovery of electricity and the subsequent advancements made by these pioneering scientists transformed electricity from a scientific curiosity into an essential tool for modern life.

Thomas Edison invented the first electric light bulb in 1879
Edison was an American inventor and businessman who developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. He was one of the first inventors to apply the principles of organised science and teamwork to the process of invention, working with many researchers and employees.
Edison's light bulb was the first that proved practical and affordable for home illumination. The key challenge was finding a filament that was both durable and inexpensive. Edison's team at his ""invention factory"" in Menlo Park, New Jersey, tested more than 6,000 possible materials before settling on carbonized bamboo.
Edison was proud of the filament's efficacy and economy, and he boasted about it to a New York Times reporter who toured the factory shortly after the successful test: "As there is no oxygen to burn," said Mr. Edison, " [the filament] will last an ordinary lifetime." He also claimed that his electric lighting system would make electricity so cheap that "only the rich will burn candles."
On December 31, 1879, Edison made the first public demonstration of his incandescent light bulb in Menlo Park. In 1880, he founded the Edison Illuminating Company and patented a system for electricity distribution, establishing the first investor-owned electric utility.

William Gilbert established the science underlying the study of electricity in the 17th century
The discovery of electricity is credited to American polymath Benjamin Franklin, who, in 1752, attached a wire to a kite in a thunderstorm, proving that lightning consists of electricity. However, the scientific study of electricity was established in the 17th century by English scientist William Gilbert.
Gilbert was born in Colchester, Essex, England, in 1544 and began studying at St. John's College, Cambridge University, when he was 14 years old. He received bachelor's, master's, and doctoral degrees, completing his studies in 1569. He then moved to London to practice as a physician in 1573.
Gilbert's principal work, 'De Magnete, Magneticisque Corporibus, et de Magno Magnete Tellure' (1600), or 'On the Loadstone and Magnetic Bodies and on the Great Magnet the Earth', gave a full account of his extensive research on electricity and magnetism. Through his experiments, Gilbert concluded that a compass needle points north-south and dips downward because the Earth acts as a giant magnet. He is known for coining the term 'electricus' in 1600, which means 'amber-like'. This term was later altered by polymath Sir Thomas Browne to electricity in 1646.
In addition to his work on electricity, Gilbert made significant contributions to the understanding of magnetism. He developed a versorium, an instrument consisting of a metal needle that could pivot freely in response to magnetic or electric fields, and a round lodestone called a terella. Through his experiments, he established the basic terminology still used in the field of electromagnetics, including electric attraction and force, and magnetic poles.
Following Gilbert's work, German scientist Otto von Guericke successfully produced static electricity by rotating a ball of sulfur. Stephen Gray discovered the difference between electrical insulators and conductors, finding that electricity could "flow along wires". These advancements, along with the work of other scientists such as Thomas Edison, Nikola Tesla, and Michael Faraday, transformed electricity from a scientific curiosity into an essential tool for modern life.

Thomas Browne, inspired by Gilbert, wrote books about electricity and coined the term
The discovery of electricity is often attributed to Benjamin Franklin, who is known for his famous kite experiment. However, it is important to recognise that the understanding of electricity was built upon by numerous scientists over time. One notable contributor was English scientist William Gilbert, who, at the turn of the 17th century, established the foundation for the study of electricity and magnetism.
Inspired by Gilbert's work, Sir Thomas Browne, an English polymath and author, further explored the concepts of electricity and magnetism. Browne's curiosity about the natural world and his broad learning across diverse fields, including science and medicine, led him to conduct investigations and write books about his findings. Browne's writings not only showcased his knowledge but also revealed a unique literary style that blended wit, subtle humour, and Baroque eloquence.
Browne's contributions to the understanding of electricity were significant. He is credited with coining the term "electricity," a word that would become central to the vocabulary of science. In doing so, he built upon Gilbert's work, who first used the Latin word "electricus." Browne's adoption and popularisation of the term "electricity" cemented its place in the scientific lexicon.
Browne's influence extended beyond his own writings. His literary style and scientific contributions resonated with future generations of writers and scientists. In the 19th century, Browne's reputation was revived by Romantics such as Thomas De Quincey, Samuel Taylor Coleridge, and Charles Lamb, who admired his work. Today, Browne's impact on the understanding of electricity is recognised, and his role in coining the term "electricity" is an enduring testament to his intellectual legacy.
Sir Thomas Browne, inspired by the groundbreaking work of William Gilbert, played a pivotal role in advancing our understanding of electricity. Through his investigations, writings, and coining of the term "electricity," Browne ensured that future generations would have a clearer understanding of this fundamental force of nature.

Ancient peoples may have experimented with electricity, as evidenced by the Baghdad Battery from 1936
The discovery of electricity is attributed to several scientists, including Benjamin Franklin, Thomas Edison, and others who built upon Franklin's work. However, the roots of electricity and electrochemical storage technologies extend far beyond modern marvels. One intriguing artifact that has captivated scientists for almost a century is the Baghdad Battery, discovered in 1936.
The Baghdad Battery, also known as the Parthian Battery, was unearthed in Khujut Rabu, located near Baghdad, Iraq, in an area steeped in historical significance. The battery consists of a clay or ceramic pot, a copper cylinder or tube, and an iron rod. This combination, when filled with a weak acid like vinegar, produces around 1 volt. The very idea that ancient civilizations might have harnessed electricity is fascinating, and the purpose of this artifact has sparked diverse theories.
Some scholars propose that the Baghdad Battery was employed for electroplating precious metals like gold or silver onto objects of lesser value. This theory is supported by the discovery of similar artifacts in nearby regions, such as Seleucia and Ctesiphon, which were sealed with bitumen, indicating the possible presence of papyrus scrolls. Additionally, the use of asphalt as a sealant and evidence of corrosion inside the jar suggest that it may have contained an acidic substance, further bolstering the electroplating theory.
However, other experts refute this theory, arguing that there is no irrefutable evidence of electroplating in the region during that time period. The battery's potential medical applications have also been explored, with suggestions that it could have been used for electrotherapy to provide pain relief and other treatments. Furthermore, the discovery of bronze and iron needles alongside similar batteries in Seleucia points to possible acupuncture practices, as were known in China during that era.
The Baghdad Battery continues to be a subject of fascination and debate, with scholars and scientists alike intrigued by the possibility that ancient peoples may have possessed a rudimentary understanding of electricity and its applications. While the true origin and purpose of the Baghdad Battery remain shrouded in mystery, it stands as a testament to the ingenuity and resourcefulness of ancient civilizations, inviting further exploration into the depths of our electrochemical past.
