Polish mathematician, specialist in control theory and ordinary
differential equations, who chaired the Organizing Committee of the 1983
Warsaw International Congress of Mathematicians.

Matters to this vault as the direct negotiator on the IMU's side of its
1979 crisis with the Soviet National Committee: per
[[entity-olli-lehto|Olli Lehto]]'s institutional history, Olech travelled
to Moscow in November 1979 on an unofficial invitation, met with
[[entity-ivan-vinogradov|Vinogradov]] and
[[entity-lev-pontryagin|Pontryagin]], and personally signed the resulting
six-point protocol that recorded the two Soviet officials' accusation of
"Zionist" influence on IMU consultative committees — not as an endorser of
that content, but as the Polish counterparty who had to carry the minute
away.
