Hi - I'm researching the history of Jews in the field of (aviation) ballooning, particularly the late 19th C and early 20th C. In collecting much information on the topic, I want to find out more about Mr Herron’s East End Scientific Toy Shop. Prior to the first world war, they exhibited at Crystal Palace (possibly the Great Exhibition or another one more science focused). And it's because of that, that a toy balloon (made by the Weinling family) they were exhibiting was seen by the military. The military part I have collected information on but I'd like to know more about the toy shop - and Mr Herron - if anyone has information.
