Ricardo Losada Márquez
Died May 2018 Bogota, Colombia
Ricardo Losada Márquez was a person of great vitality, wisdom, vision and
leadership, generous with his ideas, time, efforts and affection, who deeply
appreciated the importance and the “romance” of mathematics and mathematical
thinking as human endeavors. This led him to work decisively toward the development
of the Colombian mathematical community, presiding in a decisive era over the
Colombian Mathematics Society and realizing projects from the establishment
of the first postgraduate studies in mathematics to the founding of mathematical Olympiads in Colombia.
His vision opened up new horizons to countless young people, helping to show them what
mathematics is beyond the limited perspective prevalent in many schools. His ideas
invigorated and helped to transform mathematics in Colombia and more generally in
Latin America. He was founding member and Secretary of IACME (InterAmerican Commission
on Mathematics Education) accompanying Marshall Stone as President (1961),
remaining in that position for over a decade and working beside figures such as
Luís Santaló of Argentina and Emilio Lluís of México. He was cofounder of the
Colombian Math Olympiads (1981), of the World Federation of National Mathematics
Competitions (1984) and facilitator of the founding of the Ibero American Mathematics Olympiad (1985).
A figure consistently present at the IMO from 1981 to 2001, and at the WFNMC Congresses
from 1990 to 2014, he was a friend of many in the mathematics competition community
around the world, energetic, visionary, smiling, cheerful, optimistic and
charming. He is and will continue to be sorely missed.
