According to U.S. Census records, Abraham Isaac Gancher was born in Russia of Russian parents in about 1875. He came to the United States in 1892 and initially worked as a leather salesman. He and his wife, Rebecca Gancher, mariied in 1899. Gancher became interested in adding machines a few years later. He was active in the Automatic Adding Machine Company through at least 1918. Nobyoshi A. Kodama, who took out early patents used in the GEM, had pulled out of the picture by 1908.
Compare to 1981.0935.01.
Gancher went on to patent and sell a printing adding machine that was also sold by Automatic Adding Machine as the Gancher. See U.S. patents 1047199 (1912) and 1178227 (1916).

Hello: Abraham Isaac Gancher is my grandfather. I do not know what led me to google his name and adding machine - a fluke - but I did and was surprised - delighted - to find this page. I have a photo of him and Rebecca, my grandmother, in Central Park (they lived on the upper west side). My father, Simon Gancher, worked in the family business (industrial surplus) on Broadway until he moved us to Los Angeles for a job opportunity. I never heard of Zabriskie or Kodama, but I never heard much of anything, being the youngest of four. My father tinkered with inventions and drawings. (He went to NYU then Columbia but was pulled out of Columbia when Abraham Isaac lost everything in a gamble to buy a seat on the Exchange.) Somewhere I have a newspaper clipping about Grandpa - and the small handwriting. And why he left Russia (no surprise there). I don't know if anyone is still employed in D.C., under the current administration, but I would be open to answering any questions if the Smithsonian hasn't yet been defunded. I will respond best I can. Thanks.
