Gerson L. Schwab is a Brazilian who was born in Ponta Grossa, with Russian paternal grandmother (Germans of the Volga) and Swiss maternal grandfather. He has two children and three grandchildren. Undergraduated in dentistry, he is a specialist in orthodontics, and has been working for more than 30 years in the public and private sectors. He lives in Curitiba and since 1989 works in the Health Secretariat of Paraná State, now as a health advisor. He is affiliated to United Nations Volunteers. Master and PhD in Population and Public Health, he lived in Canada for a year, between 2012 and 2013 for a doctoral boarding (The University of British Columbia, Vancouver). He returned to this university for a postdoctoral program for another two years, from 2015 to 2017. Until 2017 he was coordinator of oral health at the 21st Regional Health in Telêmaco Borba, Brazil. He authored articles and chapters of scientific books which were published both in Brazil and abroad.

Writing on the shallowness of relationships in the postmodernity, in 2017 he published "The passion according to GLS", his first fiction work, with several quotations on which is evident his passion for Beethoven, Van Gogh and Fernando Pessoa, among others. Still on the subject of the previous book, in the following year he released "Sonnets of such brief passion", an evaluation in sonnets of the most diverse emotions. Keeping his interest for the emotions that often take the command of reason, in 2019 he published "Green is the color of passion", in which he discusses the process of liberation that imposes itself after the inevitable ruptures. The poems of these three volumes became an unplanned Trilogy of Passion.
