- Before Microsoft's Excel came about, a Harvard MBA student and his former MIT classmate built the first spreadsheet software for the Apple II.
It was 1979 and Dan Bricklin and Bob Frankston wanted to see their calculators come to life. They wanted to be able to change numbers in their calculations and update their final answers. By creating VisiCalc, the first electronic spreadsheet, that's exactly what they did.
Bricklin and Frankston would work at night because computer time was cheaper at night. They thought of it as a "visual calculator" and that is why they gave it the name VisiCalc. VisiCalc was such a crucial component of the Apple II that according to Frankston, "when Apple was going to go public, they couldn't go public until I found the last bug in the Apple II VisiCalc."

one of the greatest inventions in the birth of computing. well done guys, you deserve your truly earned place in history.
Excel is a monumental invention. It changed our business drastically. And only 15k viewers?
This isn't Excel. This is TWO generations before. First Visicalc. Then Lotus 1-2-3
I don't use spreadsheets much but when I do, I'm always amazed at how intuitive the UI is and the power they gave to people who don't really code. I do wish it the formula editor was nicer when you're dealing with long nested functions though - I end up typing it out in VSCode and pasting it back into the spreadsheet. It does also entice you into trying to write "one-liner" functions that chain multiple things together when writing a longer, multi step function can be easier to read.
I believe the "first-ever" spreadsheet was actually invented in the UK at ICI Northwich using IBM 370 mainframe and 3270 terminals in 1974 , well before these two guys (and long before the Apple II or the IBM PC). It was all written in IBM Basic Assembly language, had unlimited cells, unlimited formulae (that could be coded on up to 184 lines), was truly WYSIWYG, had backup/restore built-in, used database storage techniques and used screens with 24x80 lines allowing a much large spreadsheet page size.
The user manual for this is at the California Computer museum if you care to look. Its was called the Works Records System (WRS).
Thanks guys. We can't thank you enough. ❤️
These guys changed how mankind lived ever after!
Computer spreadsheet. I used to have a spreadsheet in my General Ledger. It was 15 columns wide by 37 lines. Granted, I had to add each column and line in my head /or calculator. But spreadsheet it was.
no words but respect for this guys
Visicalc sold Apple 2s by the truckload. Lotus 1-2-3 sold IBM PC's by the boatload.
Guys like these should be getting the credit. Not scammers like BG.
Its crazy what excel could do.
Repost but worth watching!
cool
ಅತ್ಯಂತ ಬುದ್ದಿ ಶಾಲಿ ಮಹನಿಯರೆ ನೀವು .
smart
visicacl,lotus,then excel.
The red pill
Actually it was Proffesor Richard Mattessich
Proof??
@@Vashumngam if you google 'who invented computer spreadsheets' only the name of Dan Bricklin pops out. Bob Frankston isn't mentioned. If you go to Wikipedia Frankston name pops out and there's a much less elaborate wiki on him... Professor Richard Mattesich is indeed the inventor of eletronic spreadsheets used in accounting... this according to Wikipedia. Guess it lacks something to the other two be actually recognized...
Frist!!1!!11!
