Lee De Forest quotes:

To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth - all that constitutes a wild dream worthy of Jules Verne.

While theoretically and technically television may be feasible, commercially and financially it is an impossibility.

I foresee great refinements in the field of short-pulse microwave signaling, whereby several simultaneous programs may occupy the same channel, in sequence, with incredibly swift electronic communication. [...] Short waves will be generally used in the kitchen for roasting and baking, almost instantaneously.

The children of the white families in town were not permitted to associate with me, because my father was committing the then unpardonable crime, in Southern eyes, of educating negroes.

[Man will never reach the Moon] regardless of all future scientific advances.

Short waves will be generally used in the kitchen for roasting and baking, almost instantaneously.

I am bold enough to say that a man-made Moon voyage will never occur regardless of all scientific advances.

You have debased my child....You have made him a laughingstock of intelligence...a stench in the nostrils of the gods of the ionosphere.
