From memory, the only ones who are known as the "father of calculus" are Leibniz and Newton.  So if you are going to delete any more names (unless it is an obvious one), please relocate them to the talk page, so we discuss person by person.  I'm trying to work on this page as a whole and I really only want to chip away at it a little per week.  Seeing that there are ambiguous issues with "founder" (in the title) getting confused with "father", maybe we will have to move the page to people known as the father or mother of something; but then again, in modern terms, many authors are using the term “founder” as it is more politically correct and gender neutral?  As for your deletions, I would rather like you to replace those names with who you think is the father of those subjects (and why)?  Thank you for your cooperation:  

References issue
David and Carl have jumped into this article and have somewhat demanded that every name that only has a website reference needs to be deleted.  Myself, I am new to this page (as to major edits), aside from reading it previously, and over the last five years, I understand that the standing rule at this page was that a new entry needed to have at least one reference.  Hence, if David and Carl are proposing new “reference requirements” (e.g. two or more, only book references, etc.,) then I want to hear their proposals (below) rather than just using edit comment boxes with random comments.  In this manner we can try to clean up (correct, add better references, etc.) to what we have now, and then any future additions can follow stricter rules that we all agree on.  Thank-you:
