Daniel Henry Holmes Ingalls Jr. (born 1944) is a pioneer of object-oriented computer programming and the principal architect, designer and implementer of five generations of Smalltalk environments. He designed the bytecoded virtual machine that made Smalltalk practical in 1976. He also invented bit blit, the general-purpose graphical operation that underlies most bitmap computer graphics systems today, and pop-up menus. He designed the generalizations of BitBlt to arbitrary color depth, with built-in scaling, rotation, and anti-aliasing. He made major contributions to the Squeak version of Smalltalk, including the original concept of a Smalltalk written in itself and made portable and efficient by a Smalltalk-to-C translator.
Ingalls received his Bachelor of Arts (B.A.) in physics from Harvard University, and his Master of Science (M.S.) in electrical engineering from Stanford University. While working toward a Doctor of Philosophy (Ph.D.) at Stanford, he started a company to sell a software measurement invention that he perfected, and never returned to academia.
Ingalls' first well known research was at Xerox PARC, where he began a lifelong research association with Alan Kay, and did his award-winning work on Smalltalk. He then moved to Apple Inc. He left research for a time to run the family business, the Homestead Resort, in Hot Springs, Virginia. He then worked at Interval Research Corporation, and then returned to Apple. Starting at Xerox, and then at Apple, he developed Fabrik, a visual programming language and integrated development environment (IDE), consisting of a kit of computing and user interface components that can be "wired" together to build new components and useful application software.
Then he moved to Hewlett-Packard Labs, where he developed a module architecture for Squeak. He also started and still operates a small firm, Weather Dimensions, Inc., which displays local weather data on home computers.
While best known for his work on Smalltalk, Ingalls is also known for developing an optical character recognition system for Devanagari writing, which he did at the instigation of his father, Daniel H. H. Ingalls, Sr., a professor of Sanskrit.
Ingalls has most recently moved to SAP SE Palo Alto Research Center, as a fellow. He is a key member of the Chief Scientist team guiding the company's technology vision, direction, and execution.
In 1984, Ingalls received the Association for Computing Machinery (ACM) Grace Murray Hopper Award for Outstanding Young Scientist, for his Xerox PARC research, including bit blit. In 1987, with Alan Kay, and Adele Goldberg, he received the ACM Software System Award, for his work on Smalltalk, the first fully object oriented programming software system. In 2002, he was co-recipient, with Adele Goldberg, of the Dr. Dobb's Excellence in Programming award.
