Marie Curie 

She was a French chemist and physicist. She is well known for the discovery of new elements such as radium and polonium. She also gave the theory of radioactivity as well as the isolation of radioactive isotopes. She was a Nobel Prize winner for her inventions. But due to the exposure to radiations, she died from aplastic anemia on 4th July, 1934.

Thomas Midgley 

He is known for inventing petrol and CFCs. He was a chemist and eventually got lead poisoning. This made him disabled and he got inspired to create a pulley system using ropes so that he could lift himself up from the bed. But one day, at the age of 55, he got strangled into one of the ropes of his pulley and he died.

 John Godfrey Parry-Thomas 

J.G. Parry Thomas, a Welsh engineer and motor racing driver, was inspired by his dream of breaking land speed records to invent a high-speed car. He named his creation 'Babs', which had a unique feature of visible chains connecting the wheels to the engine. Thomas aimed to surpass Malcolm Campbell's record and succeeded once, but Campbell later set a new record. While attempting to reclaim the title, a chain snapped and tragically struck Thomas' neck, resulting in his immediate death.

William Bullock 

William Bullock, born in America, is famous for inventing the rotary press for printing in 1863. This new rotating press revolutionized the printing industry with its speed and efficiency. Unfortunately, while repairing one of the press machines, Bullock's foot was crushed. He was attempting to place a pulley in the correct position when the accident occurred. Despite efforts by doctors to amputate his foot, Bullock tragically passed away during the operation.

Otto Lilienthal 

Otto Lilienthal, also known as 'The Glider King', was a trailblazer in human aviation. He achieved repeated success in gliding flights, making him the first person in history to do so. His accomplishments quickly gained worldwide fame, with newspapers and magazines publishing photographs of his gliding endeavors. This had a profound impact on people's scientific beliefs, as they began to believe that creating a real flying machine was possible. This newfound hope came after years of fantasies and unscientific claims. However, tragedy struck on August 9, 1896, when Lilienthal took a flight that reached a height of 17 meters before he tragically fell and broke his spine. He passed away the following day.

Franz Reichelt 

Otto Lilienthal, also known as 'The Glider King', was a pioneering figure in human aviation. He was the first person in history to achieve repeated success in gliding flights. His fame spread worldwide as newspapers and magazines published photographs of his glides, inspiring many to believe that creating a flying machine was indeed possible. This hope, born out of scientific evidence rather than mere fantasy, was shattered on August 9, 1896, when Lilienthal took a flight that ended in tragedy. He reached a height of 17 meters before falling to the ground, breaking his spine and ultimately succumbing to his injuries the following day.

Karel Soucek 

He was a Canadian stuntman known for his invention, the "Capsule," which he used to ride down Niagara Falls. The Capsule, similar to a barrel, was a modified version that he used for his daring stunt. Despite suffering injuries, he survived the feat. In 1985, he convinced a company to finance a barrel drop from the Houston Astrodome in Texas. They constructed a special waterfall 18 feet high with a pit at the bottom. Unfortunately, the stunt was unsuccessful, and he fell at the rim of the pool, sustaining severe injuries that led to his death the following day. In honor of his invention, the "Capsule" is now on display at the New York State Museum.

Cowper Phipps Coles 

During the Crimean War, Cowper Phipps Coles, a highly respected Royal Navy Captain, created a rotating turret for use in ships. After the war, he patented this invention and began constructing his own ships with the revolutionary design. One of these ships, the HMS Captain, required several unconventional and hazardous modifications. One such modification was the addition of a 'Hurricane Deck' that raised the ship's center of gravity. Tragically, on September 6, 1870, the Hurricane Deck caused the ship to capsize, resulting in the deaths of Cowper Coles and many others from its crew of 500.

Alexander Bogdanov 

Alexander Bogdanov, a Russian physician, economist, philosopher, writer (specializing in science fiction), and revolutionary, was known as one of the prominent Great Russian scientists. Among his various experiments, one of his notable ideas involved rejuvenation through blood transfusion. In his research, he administered blood transfusions to numerous patients, including Lenin's sister. Intrigued by the results, Bogdanov decided to try the procedure on himself, receiving a transfusion from a patient afflicted with both malaria and tuberculosis. Unfortunately, shortly after the experiment, Alexander Bogdanov passed away.

Henry Winstanley 

Henry Winstanley, a renowned English architect known for his lighthouse constructions, was responsible for the initial development of the Eddystone Lighthouse. Following its completion, he sought to assess the lighthouse's durability in various weather conditions. Consequently, he ventured inside the lighthouse during a storm. Unfortunately, the lighthouse proved unable to withstand the tempest and ultimately collapsed, resulting in the tragic deaths of Winstanley and five others.
