What was Tadao Kashio's profession? 

Casio Computer Co., Ltd.[note 1] (カシオ計算機株式会社, Kashio Keisanki Kabushiki-gaisha) is a Japanese multinational electronics manufacturing corporation headquartered in Shibuya, Tokyo, Japan. Its products include calculators, mobile phones, digital cameras, electronic musical instruments, and analogue and digital watches. It was founded in 1946, and in 1957 introduced the first entirely compact electronic calculator. It was an early digital camera innovator, and during the 1980s and 1990s, the company developed numerous affordable home electronic keyboards for musicians along with introducing the first mass-produced digital watches.

History
Casio was established as Kashio Seisakujo in April 1946 by Tadao Kashio [ja] (1917–1993), an engineer specializing in fabrication technology.[1] Kashio's first major product was the yubiwa pipe, a finger ring that would hold a cigarette, allowing the wearer to smoke the cigarette down to its nub while also leaving the wearer's hands free.[5] Japan was impoverished immediately following World War II, so cigarettes were valuable, and the invention was a success.
