The other day, Jim excitedly told me, "Did you realise I will turn x years old in the year x^2?"

He wasn't the first to think of this. The 19th century mathematician August de Morgan used to used to boast that he was x years old in the year x^2. He died in 1871.

In what year was Jim born? When will his prediction be true? In what year was de Morgan born? What is x in each case?

(In reply to Second Possibility by Ravi Raja)

Doesn't "The other day..." mean Jim said it recently? So Jim would have to be 111 years old for that to be true... and I thought that was out.
