Russell Kirsch is known for being the inventor of the pixel(像素) and, in the process of this, for inventing the world’s first digital image scanner(扫描仪). The computer scientist     1     a photograph of his infant son Walden in 1957. This was the world’s first digital image to have ever been produced. It was several decades before other early developments in     2     photography began to take shape.

“My dad was a super     3     guy, always asking Questions,” Walden Kirsch said. “He was an iconoclast(打破传统者). When people said ‘you can’t go there or you can’t do that’, he did.”

The elder Kirsch was born in New York City in 1929 to Jewish(犹太的)    4     . After graduating from the Bronx High School of Science in 1946, he     5     college at New York University, Harvard and MIT.

Kirsch made the digital imaging breakthrough(突破) six years into his 50-year career. At that time he was working in Washington, DC for the National Bureau of Standards (now the National Institute of Standards and Technology). He and his colleagues worked on a series of       6     , which involved artificial intelligence. They used the Standards Electronic Automatic Computer(SEAC), the country’s first fully operational     7     computer. It     8     about 3, 000 pounds and was able to process only a tiny part of even the most rudimentary(基) of today’s devices.

The machine detected     9     of the photograph and converted them into binary code(二进制代码) to be processed by the computer. The resulting digital greyscale image was only 176 by 176 pixels. While it was tiny by today’s standards, the image clearly     10     a recognizable reproduction of the original picture.
