Only known photo of an alleged live Tarpan, which may have been a hybrid or feral animal, 1884 Tarpan (Equus ferus ferus), also known as Eurasian wild horse, is an extinct subspecies of wild horse. The last individual believed to be of this subspecies died in captivity in Russia in 1909, although some sources claim that it was not a genuine wild horse due to its resemblance to domesticated horses.
Tiny cameras strapped to homing pigeons, a method found by Julius Neubronner and then used during WWI, 1909.
Topsy was a circus elephant killed by electrocution on January 4, 1903.
Topsy belonged to the Forepaugh Circus and spent the last years of her life at Coney Island’s Luna Park. Because she had killed three men in as many years (including a severely abusive trainer who attempted to feed her a lit cigarette), Topsy was deemed a threat to people by her owners and killed by electrocution on January 4, 1903, at the age of 28. Inventor Thomas Edison captured the event on film. He would release it later that year under the title Electrocuting an Elephant.
A means of killing initially discussed was hanging. However, the American Society for the Prevention of Cruelty to Animals protested and other ways were considered. Edison then suggested electrocution with alternating current, which had been used for the execution of humans since 1890.
Topsy was fed carrots laced with 460 grams of potassium cyanide before the deadly current from a 6,600-volt AC source was sent coursing through her body, partly as a demonstration of how “unsafe” his competitor’s (Nikola Tesla) alternating current design was. In Edison’s film she topples to the ground and is seen to move for several seconds. According to at least one contemporary account she died “without a trumpet or a groan”. The event was witnessed by an estimated 1,500 people and Edison’s film of the event was seen by audiences throughout the United States.
When Luna Park burned down in 1944, the fire was referred to as “Topsy’s Revenge”.
