All in all 288 authors popped up through this quick & dirty search.
The result should be taken with a tablespoon of salt – many names have been missed which are in wikipedia, wrong person with same name may have been queried, and there are errors in wikipedia (Year of death for Percy Bysse Shelley was given as 2010). Still, it's a start to a dreary and depressing task...
