Lebanese inventor Hassan Kamel Al-Sabbah was a pioneer in the field of electricity, with his inventions having a profound impact on 20th-century technology. Al-Sabbah, who was also an electrical and electronics research engineer, mathematician, and inventor, travelled to the US in 1921 to study at the Massachusetts Institute of Technology. He later earned a master's degree in engineering sciences from the University of Illinois in 1923 and was hired by the General Electric Company (GE) as a research engineer. Despite signing a contract with GE that gave them ownership of his inventions, Al-Sabbah's work led to numerous patents, including those related to electric cars, solar cells, and television transmission. His legacy continues to influence modern technology, and he is considered a genius whose early death in 1935 was a significant loss to the world of invention.

What You'll Learn
Hassan Kamel Al-Sabbah's work in solar energy and electric cars
Hassan Kamel Al-Sabbah was a Lebanese electrical and electronics research engineer, mathematician, and inventor. He was born in Nabatieh, Lebanon, in 1895 and studied at the American University of Beirut. In 1921, he travelled to the United States and studied at the Massachusetts Institute of Technology (MIT) for a year before enrolling at the University of Illinois, where he earned a master's degree in engineering sciences in 1923.
Al-Sabbah's work in solar energy and electric cars is particularly noteworthy. He had a dream to build sun-powered cells in the Arabian Desert, recognising that the main ingredients for solar power, sand for making solar cells, and strong sunlight for powering them, were abundant in this region. Al-Sabbah's work in solar energy is closely linked to his interest in electric cars. In 1930, he performed experiments on his own car, attempting to power it with solar energy. He worked on transforming car circuitry to make early designs for electric cars, and his innovations in this field have become extremely relevant in the modern age, where electric cars are seen as a more environmentally friendly alternative to traditional fuel-powered vehicles.
Al-Sabbah's work in solar energy extended beyond his electric car experiments. He tested solar cells that became the prototypes for those used today in space exploration and on Earth. He also developed a rectifying system that was crucial to the development of arc welding machines, which, in turn, were essential for heavy industries such as shipbuilding and the construction of tanks and turbo-generators.
Al-Sabbah's contributions to the fields of solar energy and electric cars were significant, and he is considered a technological leader whose inventions had a profound impact on the development of 20th-century technology. Despite his achievements, his work may be under-recognised due to his Lebanese origin.

His development of arc welding
Hassan Kamel Al-Sabbah was a Lebanese electrical and electronics research engineer, mathematician, and inventor. He was born in Nabatieh, Lebanon, in 1895 and studied at the American University of Beirut. He taught mathematics at the Imperial College of Damascus, Syria, and at the American University of Beirut. In 1921, he travelled to the United States and studied at the Massachusetts Institute of Technology (MIT) for a year before enrolling at the University of Illinois, where he earned a master's degree in engineering sciences in 1923.
Al-Sabbah's work in the field of arc welding was significant and had a notable impact on heavy industries. He developed a rectifying system that was crucial to the development of the arc welding machine. This system facilitated the welding of large pieces of metal required in heavy industries by using electricity to heat the metal to the required temperature for effective welding.
Al-Sabbah's rectifying system included basic patents on the vapor electric arc (1928-1930) and six patents on rectifying and rectifiers (1928-1935). These inventions became the foundation for arc-welding machines. The Assabbah rectifying system was further developed and marketed by General Electric (GE) as the GE AC/DC transformer/rectifier in 1930. This component was essential in the shield metal arc welding (SMAW) machine introduced in 1936.
During World War II, Al-Sabbah's techniques proved invaluable as industrial developers utilized them to refine mass production welding techniques for vehicles, ships, submarines, tanks, and turbo-generators for the military. The development of arc welding machinery was pivotal in advancing heavy industries, and Al-Sabbah's contributions played a vital role in this progress.
Al-Sabbah's work in arc welding was just one aspect of his broader impact on technology and industry. He held over 70 patents in various fields, including space, electric cars, and television transmission. Unfortunately, his work is often underappreciated, and his premature death in a car accident in 1935 cut short a brilliant career that could have further transformed the world of invention.

His work in television transmission
Hassan Kamel Al-Sabbah was a Lebanese electrical and electronics research engineer, mathematician, and inventor. He was born in Nabatieh, Lebanon, in 1895 and studied at the American University of Beirut. Al-Sabbah had a profound impact on the field of television transmission, with his innovations shaping the modern television landscape.
Al-Sabbah's work in television transmission is closely tied to his developments in cathode ray tube technology. He held several patents related to cathode ray tubes, which are integral components in the functioning of television screens. These patents laid the foundation for the creation of LCD (liquid crystal display) screens, which offer superior colour detail and image sharpness compared to traditional black and green filters.
Between 1927 and 1935, Al-Sabbah invented 52 different applications, and he received a total of 43 patents for his work. Among these patents were innovations in television transmission that have had a lasting impact on the industry. Al-Sabbah's work contributed significantly to the development of high-resolution LCD panels, enhancing the viewing experience for audiences worldwide.
Al-Sabbah's influence extended beyond the realm of consumer televisions. His patents in television transmission also led to the creation of military LCDs used in aircraft. These displays are designed to present information in super high detail, with enhanced colour and sharpness. This application of Al-Sabbah's work has been invaluable in military and aviation contexts, showcasing the breadth of his impact on television transmission and display technologies.
The legacy of Hassan Kamel Al-Sabbah in television transmission is undeniable. His innovations in cathode ray tube technology and LCD screens have shaped the modern television industry. Without his contributions, it is argued that modern television as we know it may not have existed. Al-Sabbah's work continues to influence the development of display technologies, solidifying his place as a pioneer in the field of television transmission.
