The day is celebrated every year as Radio Day thanks to Alexander Popov. On May 7, 1895, Alexander Popov presented a paper on a wireless lightning detector he had built that worked via using a coherer to detect radio noise from lightning strikes. The scientist also transmitted 250-meter radio signals between different campus buildings in St. Petersburg. So, Popov became a father of the first radio receiver.
