Age a fraction of the birth year

MediumBrainteasers~6m

A man's age at death equalled $\tfrac{1}{29}$ of his birth year. He was alive to celebrate a birthday in $1900$ and died before the end of World War II ( $1945$ ). How old did he turn on his $1900$ birthday?

Age at death $k$ means birth year $29k$ and death year $30k$ . Use "alive in 1900, dead before 1945".
Only $k=64$ fits (born $1856$ ). His age in $1900$ is $1900-1856$ .
