9:59:59.000,9:59:59.000 How many of you have used[br]an electronic spreadsheet, 9:59:59.000,9:59:59.000 like Microsoft Excel?[br]Very good. 9:59:59.000,9:59:59.000 Now how many of you have run a business[br]with a spreadsheet by hand, 9:59:59.000,9:59:59.000 like my dad did for his small[br]printing business in Philadelphia? 9:59:59.000,9:59:59.000 A lot less. Well, that's the way[br]it was done for hundreds of years. 9:59:59.000,9:59:59.000 In early 1978, I started working[br]on an idea that eventually became VisiCalc. 9:59:59.000,9:59:59.000 And the next year it shipped[br]running on something new 9:59:59.000,9:59:59.000 called an Apple II Personal Computer. 9:59:59.000,9:59:59.000 You could tell that things[br]had really changed when six years later, 9:59:59.000,9:59:59.000 the Wall Street Journal ran an editorial[br]that assumed you knew what VisiCalc was 9:59:59.000,9:59:59.000 and maybe even were using it.[br]Steve Jobs back in 1990 said that 9:59:59.000,9:59:59.000 spreadsheets propelled[br]the industry forward. 9:59:59.000,9:59:59.000 VisiCalc propelled the success of Apple[br]more than any other single event. 9:59:59.000,9:59:59.000 On a more personal note, Steve said[br]that if VisiCalc had been written 9:59:59.000,9:59:59.000 for some other computer,[br]you'd be interviewing 9:59:59.000,9:59:59.000 somebody else right now. 9:59:59.000,9:59:59.000 So, VisiCalc was instrumental in getting[br]personal computers on business desks. 9:59:59.000,9:59:59.000 How did it come about? What was it? 9:59:59.000,9:59:59.000 What did I go through[br]to make it be what it was? 9:59:59.000,9:59:59.000 Well, I first learned to program[br]back in 1966, when I was 15 -- 9:59:59.000,9:59:59.000 just a couple months after[br]this photo was taken. 9:59:59.000,9:59:59.000 Few high schoolers had access[br]to computers in those days 9:59:59.000,9:59:59.000 but through luck[br]and an awful lot of perseverance, 9:59:59.000,9:59:59.000 I was able to get[br]computer time around the city. 9:59:59.000,9:59:59.000 After sleeping in the mud at Woodstock,[br]I went off the MIT to go to college, 9:59:59.000,9:59:59.000 where to make money,[br]I worked on the Multics Project. 9:59:59.000,9:59:59.000 Now Multics was a trailblazing[br]interactive time-sharing system. 9:59:59.000,9:59:59.000 Have you heard of the[br]Lenix ad Unix operating systems? 9:59:59.000,9:59:59.000 They came from Multics.[br]I worked on the Multics versions 9:59:59.000,9:59:59.000 of what are known as[br]interpreted computer languages, 9:59:59.000,9:59:59.000 that are used by people[br]in non-computer fields 9:59:59.000,9:59:59.000 to do their calculations while seated[br]at a computer terminal. 9:59:59.000,9:59:59.000 After I graduated from MIT, 9:59:59.000,9:59:59.000 I went to work for[br]Digital Equipment Corporation. 9:59:59.000,9:59:59.000 At DEC, I worked on software for[br]the new area of computerized typesetting. 9:59:59.000,9:59:59.000 I helped newspapers replace[br]their reporters' typewriters 9:59:59.000,9:59:59.000 with computer terminals. 9:59:59.000,9:59:59.000 I'd write software[br]and then I'd go out in the field 9:59:59.000,9:59:59.000 to places like the Kansas City Star where[br]I would train users and get feedback. 9:59:59.000,9:59:59.000 Now this was real world experience[br]that was quite different 9:59:59.000,9:59:59.000 from what I saw in the lab at MIT.
