In 1935, Du Bois wrote an article that said,
"We don't need
integrated schools we need good schools"
and there were many people who interpreted
that to mean that he was anti-desegregation when in fact one of
the things that authors have written
looking retrospectively at the
whole Brown Vs. Board of Education fight,
he wrote this in 1935,
20 years before the Brown decision,
that we don't talk about education as a
qualitative issue, we don't talk about
education as a political issue, but in
point of fact, the reason why Brown has
failed
or, in some respects has failed, is because
there was a
moving away from considerations of
political implications of education.
So Du Bois actually did speak about that
many times, but his most famous one
was when he wrote 
"Does The Negro Need Separate Schools?"
And he said they need separate schools if they're not going to be
educated in integrated schools, then yes
they do need separate schools
