Johannes Fransiscus (Joop) den Tonkelaar was a renowned Dutch meteorologist and television pioneer born on January 4, 1926, in Leiden. He was known as 'de Arm' due to his distinctive appearance on screen where only his arm and a weather map were visible. He was a pacifist during World War II and had a keen interest in meteorology, which led him to publish a significant work entitled 'Middelen en Mogelijkheden der Meteorologie' in 1955, exploring weather forecasting and atmospheric science.
