Setting all the details aside, there are about 30 years between the first column-oriented database and MonetDB. Databases are a really well and early researched area of computer science and many ideas existed at least in the academic area for decades before they saw widespread adoption. Another example is what we now label NoSQL databases, they also already existed in the 1960s.

MonetDB in its current form was first created in 2002 by doctoral student Peter Alexander Boncz and professor Martin L. Kersten as part of the 1990s' MAGNUM research project at University of Amsterdam. [1]

TAXIR was the first application of a column-oriented database storage system with focus on information-retrieval in biology in 1969. [2]
