Alexander Graham Bell

Observation, not old age, brings wisdom.

It is the man who carefully advances step by step...who is bound to advance in life and the man who uses the principles that he has discovered about the success of others, and applies them most wisely and intelligently to his own conduct, will most certainly get along.

I have heard articulate speech produced by sunlight. I have heard a ray of the sun laugh and cough and sing.

The phonograph will undoubtedly be the means of great good to education.

Morse conquered his electrical difficulties, though he was only a painter, and I do not believe that there is any so-called cultivation that can be effected in man or woman that cannot be overcome.

The telephone is only one invention among many, but it is the one that has had the most profound effect on human life.

Education should be so directed as to develop the powers of the individual rather than to store up in his mind a vast amount of unrelated facts.

The final result of our researches has widened the class of substances sensitive to light vibrations, until we can propound the fact of such sensitiveness being a general property of all matter.

I do not want to be remembered as the man who invented the telephone, but as the man who brought the deaf to hear.

The deaf community must be preserved as a distinct group with its own culture and language.

Aerial locomotion is not a mere dream of the inventor, but a reality which is already in course of accomplishment.

The hydrofoil boat will revolutionize water travel.

There is no place like home.

My knowledge of electrical phenomena came from the study of Professor Henry's experiments.

The telephone was invented to speak across distances, but it has brought the world closer.

Invention is the talent of youth, and judgment that of age.

The love of one's country is a splendid thing, but it is not to be supposed that it extends to everything.

I am a believer in the genius of the people.

The true measure of a man is how he treats someone who can do him absolutely no good.

Every good thing that has been invented was first thought of by someone who had the courage to try.
