Daniel Henry Holmes Ingalls, Jr. is a pioneer of object-oriented computer programming and the principal architect, designer and implementor 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 graphics systems today, and pop-up menus.

  • Daniel Henry Holmes Ingalls, Jr. is a pioneer of object-oriented computer programming and the principal architect, designer and implementor 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 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. His major contributions to the Squeak system include the original concept of a Smalltalk written in itself and made portable and efficient by a Smalltalk-to-C translator.
  • Dan Ingalls on yhdysvaltalainen olio-ohjelmoinnin pioneeri ja viiden eri Smalltalk-ohjelmointikielisukupolven pääarkkitehti, -suunnittelija ja -toteuttaja. Hän kehitti tavukoodatun virtuaalikoneen, joka teki Smalltalkin hyödylliseksi 1976. Ingalls myös kehitti yleisen bit blit-operaation (BitBlt, Bit-Block Transfer), jota nykyään käytetään graafisissa sovelluksissa, tyypillisesti bittikarttojen ja ponnahdusmenujen kanssa.
  • Daniel Henry Holmes Ingalls, Jr. invente en 1974 un système logiciel de fenêtres superposées et menus déroulants.
