The was a controversy between Hamilton and Heavyside about the use of 
quaternions (which Hamilton had invented).

Vectors have won.

The event was in the late 19th century, but actually I don't know 
exactly when.

Also 170 is a little less than two centuries - but that is not really 
important..

This absolutely nothing to do with the question, whether the quantity 
'work' is a vector quantity or a scalar.

The idea of work as a scalar is based on the idea of distance is a vector.

Only: this is not the case, since 'vector' in physics is shorthand for 
'vector quantity', not for 'little arrow, pointing in a certain direction'.
