Juan Tesoro (Almería, Spain 1936 - Madrid 2009) was deeply fond on studying philosophy. He was also a man of science. After he graduated as engineer he worked in different positions at the Spanish industrial sector.

He was pleased to write the essay entitled "For an empirical reading of physics" (see below to find a copy). When finished Juan said "I have finally removed a little stone that I had inside my shoe" (NOTE: This "About me" has been written by his living son Rafael Tesoro)
