Lastly just to note, if you access the listing for Graham you get a questionnaire prompt asking why you are interested in this topic. How very interesting!

I agree.

Everything that happened has a basis in the past.

Learning about the people who worked on these products is sometimes very informative

Upon request of Cohen van der Eb returned to the Netherlands in 1970 to start a research group in molecular biology of oncoviruses.[2] During this period Canadian post-doc Frank L. Graham joined his research group.[4] Together they worked on a technique to insert foreign DNA in cultured human cells. The technique of calcium phosphate transfection became available in 1973.[5][6][7] Fellow molecular biologist Piet Borst called this discovery of how to insert foreign DNA in human cells the cornerstone of genetics and cell biology.[3][8] In 1972 van der Eb obtained and managed to culture embryonic kidney cells from an aborted or miscarried human foetus.[9][10] With Graham's contributions in transfection of the cells with the adenovirus 5 this led to the cell line of HEK 293 cells.[4][11] HEK 293 became one of the most used cell lines worldwide, coming close to the use of the HeLa cell line.[9] In 1974 van der Eb and Graham demonstrated that loose virus DNA could cause cancer.[5]

Just to note, Frank l Graham has a very interesting nondescript past considering he was part of a cornerstone to virology.
