For the following sentence, I would like to find a good word for "beginning". In German, we for example have "Geburtsstunde" which means "hour of birth", and I would like to find a similar word.
"The ... problem has been thoroughly studied ever since the beginning of the studies of graph theory."
I am completely unsure how to write this sentence and it is also fine to completely change it, but I really would like it to sound "great", as it is planned to be the first sentence of the introduction in a paper.
Thank you very much for your help!
