The Story of Plumb Bob

Contrary to popular belief, Plumb Bob is not a mystical secret society made up of a few members all going by the name Robert Plumb. In truth, veterans of World War I formed the organization of Plumb Bob. These young men returned home as war heroes, but soon found that they had forgotten some of the knowledge they had gained in the pre-war times.

In spite of rigorous efforts by these brave veterans, University of Minnesota physics got the best of them. They failed the class and became destined to one more year of the course with an entirely different class of students. The young men who had failed together formed the society of Plumb Bob. New members were warmly welcomed if they met the requirement: to have failed a U of M math or physics course. The members of this group originally met at a bar on East Hennepin to discuss problems relating to their own lives and to the world in general. Over time the meeting places changed, but the kind of people in the society did not. The "failure" requirement was eventually dropped in favor of a GPA of at least 3.14, which is the value of pi. Thus, Plumb Bob became an Honorary Leadership Society.

Since the beginning, Plumb Bob has had the honor of guarding the sacred Blarney Stone. The Blarney Stone is the dearest of all things to a true engineer. The significance of the great Blarney Stone lies in its inscription and history. It is inscribed with the foundation of all engineering: "Erin go Braugh," which can be loosely translated as, "St. Patrick was an engineer!" This is why we pay homage to St. Patrick: he is the patron saint of all engineers.

During the early years of the society, the members of Plumb Bob would carry the Blarney Stone out of hiding and display it on their float in the Engineer’s Day parade. All of the engineers would pay tribute to the stone on this day, and in return would be granted the highest of all honors: to kiss the Blarney Stone. At the end of the parade the stone was presented to the gentleman lucky enough to have been dubbed St. Patrick for the knighting ceremony. At the end of the night, the Plumb Bobbers would steal off into the darkness to hide the Blarney Stone for one more year.

For many years the School of Mines was quite envious of the Engineers’ sacred Blarney Stone. They began a ritual of attempting to steal the stone from the Bobbers’ determined care. On many occasions they were even successful. This turned into an annual event that culminated in the Miners’ attempt to crush the stone at a local quarry. Fortunately, the members of Plumb Bob learned of this terrible event before it was to happen, and replaced the true Blarney Stone with a fake. Much to the miners’ chagrin, the sacred Stone was safe.

After the School of mines dissolved (many years ago), the Foresters and Law students took over this tradition of trying to steal the Blarney Stone. For decades the Foresters were the chief rivals of Plumb Bob and all engineers. Yet, the inevitable finally occurred: the strength of the Forestry Club waned, while Plumb Bob and Engineers remained strong. It is in this spirit that the early celebration of Engineers began, and in this strong spirit that we continue to celebrate what has become CSE Week.
