Final answer:
The reference material provided does not mention an individual who was blind from glaucoma and received excellent music training in their teens. The text discusses Isaac Newton and Albert Einstein, both of whom are celebrated for their scientific contributions, not for music training.
Step-by-step explanation:
The individual who received excellent music training in his teens, though blind from glaucoma from the age of seven, is not mentioned in the provided reference material. The reference material discusses Isaac Newton and his accomplishments in the fields of mathematics and physics, as well as Albert Einstein's educational background and early career. Neither Newton nor Einstein fits the description of being blind from glaucoma and receiving music training; their achievements lay in scientific fields. The question appears to allude to a historical figure in the field of music or arts, but this is not covered by the information given.
