In the following year, 1849, Pierre Foucauld, a blind
pupil of the Institut des Aveugles, of Paris, invented a
machine for the use of those who shared his terrible
affliction. He exhibited it in Paris, and was awarded a
gold medal. In the next year, the Board of Encourage-
ment, Paris (would that we had such a Board in this
country! ) also conferred a medal upon him. A year
passed, and he brought the machine to the Great Exhibition
of 1851, to again obtain recognition and reward. A number
of Foucauld’s machines were made, at a price of £20 each.
Being somewhat bulky, they were placed upon a low stool,
in front of which stood the operator. Cassell’s Illustrated
Exhibitor has preserved to us a picture of the machine,
which is herewith reproduced. K is a keyboard with two

slide that was fitted into one of a number of radial grooves
in the machine. The free end of the slide carried a matrix
agreeing with the key, and at the surface of the sheet of
paper, C, the radial grooves all met, and coincided, so that
pressure upon any one of the keys produced an embossed
letter on the paper at that point. Of course the paper
was advanced a step after each letter, and means were
provided for shifting the paper for the line-space.
Keeping to our chronological order, we find that in
1850, Mr. Eddy, of Baltimore, obtained a patent for what
he called a printing machine, but which was, in reality,
a typewriter.
The machine was provided with seventy-eight types,
arranged in the type-form in six rows of thirteen each.
The form consisted of two horizontal steel plates, one above
the other, one and three-fourths inches apart, and connected
by columns at the angles. The top plate, a, is shown,
