Deletion of Abol Hussein Tanhai

Comment: Fails , which states {{tq|" Ordinary colloquia and seminar talks and invited lectures at scholarly conferences, standard research grants, named post-doctoral fellowships, visiting appointments, or internal university awards are insufficient for this purpose."}} They appear to have attained 'Assistant Professor' and 'Visiting Professor' status, so I think they fail that criterion. There are insufficient sources to check from the article, but I could find nothing significant on Google or in Google Books about them. Cutting through all the uncited waffle (which I was sooo tempted to excise), they appear to have written numerous books and published papers - but many academics do that, and that doesn't confer notability, per se. Have they made a significant impact on their subject area to the point of meeting ? I struggle to find anything to help me one way or another - so I fall on the side of non-notability at this time
