David Ingalls Bell is a Life enthusiast who was born and educated in the United States but now lives in Australia. He has discovered and helped construct some of the most interesting known patterns, with a heavy focus on spaceships. He contributes to the forums under the username dbell. He has also created multiple new sawteeth, often with new and interesting properties, such Sawtooth 1163 and the Moving sawtooth, the first sawtooth spaceship.
In 2004, he and Jason Summers helped Gabriel Nivasch build caterpillar; the first 17c/45 spaceship to be constructed. He also found 25P3H1V0.2, one of the smallest-known c/3 orthogonal spaceships, and spider, the smallest-known c/5 orthogonal spaceship. He has also found several patterns that are the first examples of spaceships with their particular speed and period: c/2 orthogonal period 22, c/2 orthogonal period 26, c/3 orthogonal period 12, c/4 orthogonal period 20, 2c/5 orthogonal period 10, c/5 orthogonal period 30 (with Noam Elkies), c/3 orthogonal period 36, c/3 orthogonal period 24, c/3 orthogonal period 15, c/2 orthogonal period 6, and c/3 orthogonal period 9.
He was the first person to explicitly construct a unit Life cell: the p5760 unit Life cell. Other notable constructions include the infinite glider hotel and moving sawtooth.
He also has explored some other Life-like cellular automata in some depth, most notably HighLife.
