Think about this...

The first computer, an IBM 610, was acquired for student use in 1960.

In 1966 the IBM 360/75 was purchased for $3 000 000 more than the entire MC building. It was the largest computer in Canada and housed in the infamous Red Room.

In the 1980's, the University of Waterloo was producing roughly one third of Canada's computer science graduates.

Back in the 1970's-1980's, any student that could demonstrate crashing the computer system was treated to a drink for exposing a weakness. To future students: this policy is no longer valid.

The pink tie originated as one of Ralph Stanton's eccentric habits. It is speculated that the founder of the Math Faculty merely did his laundry in the runoff from a red roof after a friend accidentally dyed his undergarments a similar colour while staying there.

Waterloo's developments

Waterloo established Canada's first Bioinformatics undergraduate degree program.

Waterloo had a hand in creating both Maple Software and OpenText. Maple Software spawned from a symbolic algebra system created here and OpenText was a spin off of the project to computerize the Oxford English Dictionary.

Some Academy Award winners are graduates of Waterloo's Computer Graphics Lab. This is the same lab that has created a computer brush model that learns to mimic the style of its user.

Amazing accomplishments

Tony Lai

Mr. Lai is the youngest graduate student of the University. He was only 14 years, 9 months old when he entered Waterloo. He was only 18 years, 5 months old when he successfully defended his thesis, "Efficient Maintenance of Binary Search Trees", in 1990 - the same age as the average first year student.

Marceli Wein

Marceli Wein, adjunct professor of computer science, won an Academy Award in 1997 shared with Nestor Burtnyk for their work on computer assisted key framing for character animation. A demonstration of this technique can be found below.


I often fancy that the most practical thing in the world is a good general theory when it’s continually tested and refined against reality.

We have heard about prime numbers

And the squaring of the cube

And the good life at U of Waterloo

Hard won funding

It's 1966. The Government of Ontario is willing to pay 90% of the cost of all university buildings, including furnishings. The University of Waterloo needs a larger, faster computer.

Wes Graham has the solution. After meeting Wes Graham to hear him out, the minister of education announces the University of Waterloo's plans for a new Math and Computer building have been approved for funding.

Included in the plans was the "IBM 360/75", the largest and fastest computer ever installed in Canada. It was carefully marked under "furnishings", ensuring 90% payment by the Government of Canada.

Logo for the Graphics Group

Kelly Booth invited all the grad students from the Graphics Group to a party at a friend's. He mentioned that the friend was a fan of pink flamingos. He did not mention that the friend was unaware of the party's existence.

The next morning, 40 pink flamingos were found on the host's front lawn. As long as the flamingos lived, they attended every single graphics party (upwards of five years). The pink flamingo logo remains to this day.
