ts range and improving the apparatus. One
great difficulty involved was in increasing the power of the sending
apparatus. Greater range has been secured in wireless telegraphy by
using stronger sending currents. But the delicate microphone would
not carry these stronger currents. Increased sensitiveness in the
receiving apparatus was also necessary.

Not content with their accomplishments in increasing the scope of the
wire telephone, the engineers of the Bell organization, headed by
John J. Carty, turned their attention to the wireless transmission
of speech. Determined that the existing telephone system should be
extended and supplemented in every useful way, they attacked the
problem with vigor. It was a problem that had long baffled the keenest
of European scientists, including Marconi himself, but that did not
deter Carty and his associates. They were determined that the glory of
spanning the Atlantic by wireless telephone should come to America
and American engineers. They wanted history to record the wireless
telephone as an American achievement along with the telegraph and the
telephone.

The methods used in achieving the wireless telephone were widely
different from those which brought forth the telegraph and the
telephone. Times had changed. Men had found that it was more effective
to work together through organizations than to struggle along as
individuals. The very physical scope of the undertakings made the old
methods impracticable. One cannot perfect a transcontinental telephone
line nor a transatlantic wireless telephone in a garret. And with a
powerful organization behind them it was not necessary for Carty
and his associates to starve and skimp through interminable years,
handicapped by the inadequate equipment, while they slowly achieved
results. This great organization, working with modern methods,
produced the most wonderful results with startling rapidity.

Important work had already been done by Marconi, Fessenden, De Forest,
and others. But their results were still incomplete; they could not
talk for any considerable distance. Carty organized his staff with
care, Bancroft Gerhardi, Doctor Jewett, H.D. Arnold, and Colpitts
being prominent among the group of brilliant American scientists
who joined with Carty in his great undertaking. While much had
been accomplished, much still remained to be done, and the various
contributions had to be co-ordinated into a unified, workable whole.
