Origin & Claim

How and when did the tradition of fortune cookie started?
Although it is commonly served at Chinese Restaurants, the tradition of fortune cookie did not come from China.
There is a similar (but not the same) version of fortune cookie in Japan, in which a piece of paper with fortune (which can be fortune, misfortune or somewhere in the middle) is placed in a Japanese-style cookie.
According to Wikipedia, number of people claimed to have introduced fortune cookie:
* Makoto Hagiwara: Golden Gate Park’s Japanese Tea Garden, San Francisco, 1890s or early 1900s
* David Jung: Hong Kong Noodle Company, Los Angeles, 1918
* Seiichi Kito: Fugetsu-do of Little Tokyo, Los Angeles
