For the Batavian Society of Experimental Philosophy. The engine was ordered by Stephen Hoogendyk, but on account of his great age he passed the arrangements for the engine to the Directors of the Batavian Society of Experimental Philosophy and J. D. H. van Liender. The engine was erected near Rotterdam, to drain the polder of Blydorp and Kool. It was frequently referred to as being for the "Batavian Government", hence its code, "BG".
