I agree that you have found someone who may have signed the album as Hersz Korn! In 1941 he would have been 15 years old, the right age to attend school #2. In the future, please remember to leave a comment explaining how you decided this was the right student.
You might also want to look at Hersz Ela Kron, born in 1931, as another possible candidate.
I look forward to seeing what you find in the next stages!
