Co-discovered two new chemical elements, technetium and astatine, and later the antiproton, sharing the 1959 Nobel Prize in Physics for the antiproton discovery.

Persuaded Ernest Lawrence in 1936 to let him take discarded, cyclotron-irradiated molybdenum parts back to his under-resourced Palermo laboratory specifically to search for undiscovered radioactivity in them -- the act that directly led to the technetium discovery.

At a contentious 1970 Berkeley meeting over splitting the Livermore weapons lab from the pure-science lab, spoke up decisively against his own reputation for caution: "Logic argues for separation... If funding suffers, so be it" -- a position credited with carrying the vote.

Taking a decisive public stance at a high-stakes institutional meeting, against his usual caution, is part of the basis for the profile's decisiveness score. Decisiveness

A National Academy of Sciences memoir directly describes him as "proud, aloof, and somewhat intimidating," a pattern the memoir traces to his feeling insufficiently recognized for the technetium discovery -- his own son separately described him as "often remote, preoccupied with work and critical rather than encouraging."

This documented, sustained interpersonal pattern -- corroborated independently by his own son -- is part of the basis for the profile's conflict_tolerance score, scored dual-edged rather than a simple advantage. Conflict Tolerance
