As I understand it, today's professors spend a large amount of time writing grant applications, many of which fail. As a result, I'm thinking of endowing a professorship someday with enough funds to remove this part of the job description - effectively funding the professor for as long as they hold the professorship.
One thing I'm concerned about is that this would also be removing a critical part of the job. For example this job advertisement for a senior lecturer/associate professor explicitly asks for "A proven record of attracting external funding for research". In that case, the professor would never pass this requirement since they would have no experience at writing grant applications, let alone actually getting the funding.
Question: is this a legitimate concern? If so, are there any obvious solutions? This should only matter if the professor leaves the professorship, and presumably that is not likely to happen, but I'd still rather the professorship not become a position which one can enter but not leave because it makes one uncompetitive on the market.
