Walter Zapp was a Latvian inventor born on the 4th September 1905.
In 1936, he invented a prototype camera which was smaller than a Cigar and weighed less than lighter, this was quite a revelation and was considered to be the first ‘spy’ camera.
‘This camera was developed into a revised version, which later became known as the so-called Riga MINOX, named after the capital of Latvia.’ (https://www.minox.com/en/about/walter-zapp/,2020)
It’s so interesting to see where the idea of surveillance through hidden cameras began, as in a way this is where it started for the public to able to surveille others, before it was almost like only the governments were able to do that, but not anymore.
