We recall the personality andscientific achievements of Professor Oleg Konstantinovich Tikhomirov, wholectured for six months in Mexico. During this period he developed atheoretical basis for psychology at the Autonomous University of Puebla (UAP).In his academic work at UAP, he established historical-cultural foundations forpsychology's activity theories (ATs), which since his demise have beendistributed throughout Mexico and Latin America. Beyond his effect on thecultural traditions of psychology, Prof. Tikhomirov has had an abiding impacton the ways of thinking and has created an 'image for the world' (to use anexpression coined by A.N. Leontiev).We should begin by explaining howTikhomirov could in such a short timespan implement his work at Puebla. Thisexplanation might help the reader grasp the depth of our respect for OlegKonstantinovich. However, prior to that step, we should study the professor'srelationship with the article's authors, Luis Quintanar Rojas and his wifeYulia Solovieva. Luis Quintanar, a participant in the Master Degree program inPsychobiology at the Faculty of Psychology, National Autonomous University ofMexico, sought to continue his higher education by studying A.R. Luria'sconcepts of neuropsychology.Consequently, he applied to the SovietUnion in 1988 and was granted a scholarship to Moscow State University (MSU).During Quintanar's four years in the Soviet capital, Prof. Tsvetkova supervisedhis Ph.D. dissertation. After defending his doctoral tract, Quintanar returnedto Mexico in 1992. There he secured employment at UAP and also established aMaster's Program (MP) in Neuropsychological Diagnosis and Rehabilitation.Launched in August, 1994, the MP initially had only one teacher and researcher:Luis Quintanar himself. At that stage, the program had yet to employ otherteachers or representatives of historical-cultural psychology (HCP) or ofneuropsychology. As a result, it was forced to invite teachers from otherMexican universities or from abroad. Several local researchers were asked tocollaborate in the MP's lecturing, but none was well acquainted with HCP orwith neuropsychology. Quintanar had always planned for the program to embracegraduate students of psychology seeking an HCP orientation in general, andLuria's approach in particular. But the only way to attain this objective wasto seek financial aid from Mexico's National Counsel of Science and Technology(CONACYT). Such assistance would also attract professors from MSU to lecture onneuropsychological and psychological concepts.The neuropsychological-orientedprogram started receiving CONACYT support in 1995, with the financial aid usedby local students (who applied for government scholarships), and by foreignteachers and researchers. The first priority was to deal with topics such asneuropsychology, with Prof. L.S. Tsvetkova invited to Mexico. She arrived atPuebla with her husband in 1994 and stayed until 1996.O.K. Tikhomirov, Luis Quintanar(O.K. Tikhomirov, Luis Quintanar)Tsvetkova was primarily invited due tothe close scientific bond she had developed with Quintanar during his doctoralstudies at MSU.The latter sought her advice onsubjects beyond the MP, including the invitation from MSU of specialists ingeneral and developmental psychology. So it happened that Prof. Tsvetkovaadvised Quintanar to invite Prof. O.K. Tikhomirov to lecture in generalpsychology, and Prof. V.Ya Liaudis to teach both pedagogical and developmentaltopics. Oleg Konstantinovich had served as the 'methodological supervisor' forQuintanar's Ph.D. dissertation at MSU.The following two photographs showQuintanar defending his Ph.D. dissertation at MSU on June 5, 1992.It is important to relate thatCONACYT's financial support was secured for air tickets and salary alone. Inthe case of L.S. Tsvetkova, it authorized a two-year salary, while forTikhomirov, it only authorized a six-month salary (such types of financialsupport are at present even more difficult to attain). …
