Align composer name tag

[Jefferson dos Santos Felix]

I try to put the composer's year of birth and death below his name,
right-aligned, but I can't do it.
See the attempt below:

\version "2.4.1"
\header
{
        title = "A Title Song"
        composer = \markup \column <{"Composer Name"}  {\right-align 
"(1900-1950)"}>
        poet = "J.S.F."
}
\score {c'}
 
Is anything wrong?

Thaks,
