This machine is the prototype of the motion picture projector in

universal use the world over, the result of experimentation begun by

Mr. Jenkins in 1890; the machine finished and publicly exhibited in

1893 and 1894. Later shown before the Franklin Institute, and

thereafter in the U. S. National Museum. When it has completed its

service in the Laboratory office, the Franklin Institute Museum will

be the final depository.

Later, in making a second award, that of the John Scott Medal, “in

recognition of the value of this invention,” the Institute Committee

said: “Eighteen years ago the applicant exhibited a commercial

motion picture projecting machine which he termed the ‘Plantoscope.’

This was recognized by the Institute and subsequently proved to be

the first successful form of projecting machine for the production

of life-size motion pictures from a narrow strip of film containing

successive phases of motion.”
