Where and when was first ever intradermal penicillin sensitivity test given ?

At NYC's Columbia-Presbyterian Hospital, on  October 16th 1940.

In fact it was the historical first ever antibiotic injection given to a patient (two patients actually) followed up a few hours later, after no reaction was observed, by a larger (and later still larger) doses given subcutaneously.

Amazingly, Dr Martin Henry Dawson's careful and cautious technique on that historical day are still followed to the letter by all well trained nurses and doctors....
