(1882 - 1969 ) World War I totally disrupted the mathematical
communities of eastern Europe. Rather than try to re-build
comprehensive university programs in several areas of research,
Sierpinski, Kuratowski, Banach and others decided to work
together in the emerging field of abstract spaces. They soon
became known as the "Polish School." Their first international
recognition came from publishing a new journal, Fundamenta
Mathematicae (1920), devoted to set theory and related topics,
and not to their work in topology. Indeed, the publication of
Banach's dissertation in 1922 has been called the birth of
functional analysis. interest in abstract spaces flourished. As
early as 1915, Sierpinski described a "gasket" or a "triangle"
with repeated and proportionally reduced areas. Today these
shapes are widely known as "fractals." Sierpinski's triangles
would later emerge to be among the most recognizable shapes or
