Web Search 

You can also try searching the web for information about your mathematician. Please keep in mind that anyone can post anything on the web, so you’ll need to carefully review the content you decide to use.  

One trick you can try to make sure that you only receive results from credible sources, such as government or educational websites, is to add site:.edu or site:.gov to your searches. This tells the search engine that you only want to see resources from these domain types.
