Father of IBM Fortran System dies

#1 Post by ryengineer » Wed Mar 21, 2007 2:24 am

I learned Formula Translation (Fortran) as a youngster, losing such a brilliant mind is very sad.

May his soul Rest in Peace, AMEN!

John Backus, whose development of the Fortran programming language in the 1950s changed how people interacted with computers and paved the way for modern software, has died. He was 82.

Backus died Saturday in Ashland, Ore., according to IBM Corp., where he spent his career.

Prior to Fortran, computers had to be meticulously "hand-coded" — programmed in the raw strings of digits that triggered actions inside the machine. Fortran was a "high-level" language because it abstracted that work — it let programmers enter commands in a more intuitive system, which the computer would translate into machine code on its own.

"It was just a quantum leap. It changed the game in a way that has only happened two or three times in the computer industry," said Jim Horning, a longtime programmer who co-chairs the Association for Computing Machinery's award committee.

That organization gave Backus its 1977 Turing Award, one of the industry's highest accolades. Backus also won a National Medal of Science in 1975 and got the 1993 Charles Stark Draper Prize, the top honor from the National Academy of Engineering.

"Much of my work has come from being lazy," Backus told Think, the IBM employee magazine, in 1979. "I didn't like writing programs, and so, when I was working on the IBM 701 (an early computer), writing programs for computing missile trajectories, I started work on a programming system to make it easier to write programs."

John Warner Backus was born in Wilmington, Del., in 1924. His father was a chemist who became a stockbroker. Backus had what he would later describe as a "checkered educational career" in prep school and the University of Virginia, which he left after six months. After being drafted into the Army, Backus studied medicine but dropped it when he found radio engineering more compelling.

Backus finally found his calling in math, and he pursued a master's degree at Columbia University in New York. Shortly before graduating, Backus toured the IBM offices in midtown Manhattan and came across the company's Selective Sequence Electronic Calculator, an early computer stuffed with 13,000 vacuum tubes. Backus met one of the machine's inventors, Rex Seeber — who "gave me a little homemade test and hired me on the spot," Backus recalled in 1979.

Backus' early work at IBM included computing lunar positions on the balky, bulky computers that were state of the art in the 1950s. But he tired of hand-coding the hardware, and in 1954 he got his bosses to let him assemble a team that could design an easier system.

The result, Fortran, short for Formula Translation, reduced the number of programming statements necessary to operate a machine by a factor of 20.

Even more importantly, "it took about as long to write one line of Fortran as one line of assembly code," Horning said. Previous attempts at high-level language had failed on that count, so Fortran showed skeptics that machines could run just as efficiently without hand-coding.

From there, a wide range of programming languages and software approaches proliferated, although Fortran also evolved over the years and remains in use.

Known as a maverick who preferred jeans to IBM's buttoned-up, conservative style, Backus stayed with the company until his retirement in 1991. Among his other important contributions was a method for describing the particular grammar of computer languages. The system came to be known as Backus-Naur Form.
"I've come a long, long way," she said, "and I will go as far,
With the man who takes me from my horse, and leads me to a bar."
The man who took her off her steed, and stood her to a beer,
Were a bleary-eyed Surveyor and a DRUNKEN ENGINEER.

:-(

I knew about this piece of news but why did you bring up this topic over here and make me feel sad? :cry:

May his soul rest in peace. God bless him. *bow head and mutter AMEN* :cry:

Fortran--the first language

Fortran was my first language, and the only language I consider myself truly fluent in.

RIP John Backus

It was my second language, after BASIC. Used to be a FORTRAN programmer at NASA-Ames and then at Fairchild. I miss using it!

The first computer I ever saw and ever worked with used Fortran. Punch cards, endless loops, a computer that filled an entire room with a hard drive the size of a car tire(probably about 1G). I think it was a Singer computer.
First thing we did was figure out how to hack the program that sent the absent student list to our homeroom teachers. So hat's off to Mr. Backus for opening the door to the computer age to a couple of high school kids with grease under their fingernails from working on their old Chevys(and getting us a couple days off from school while we were learning about it).

FORTRAN on an IBM 1130 in 1978 ... and later WATFIV (Waterloo Fortran IV).

Sorry to hear of his passing... his work has touched such an incredibly large number of people.

I remember using FORTRAN for the first time on a DEC PDP-8 in 1969.

When I started working on IBM mainframes (back in 1968), we were only allowed to use Assembler. I'd heard about Fortran but never got to try it. Instead I also acquired RPG II, followed by Cobol and PL1.
Cobol is my 'native' language nowadays, followed by Assembler.
And I dabble in HTML, JS, CSS etc. on the side, doing websites.

Anyway, if it weren't for the likes of Mr. Backus and Mrs. Grace Hopper, my working life would not be half as interesting and rewarding as it has been so far.
