Oscar Antonio Klein, an agronomist and significant contributor to Argentina's wheat history, died on February 3 at the age of 84. As part of a pioneering family in the national seed industry, he took over the Klein Breeding Company as technical director in 1970, succeeding his father Enrique Klein, who founded the company in 1919. Under his leadership, the company saw the development of various wheat cultivars that became integral to Argentine agriculture.

Klein's influence on the wheat industry is evident through the more than 119 wheat cultivars registered in the country over the last century, starting with the historic variety 'Favorito' in 1920. His work not only advanced wheat breeding but also significantly impacted crop yields and agricultural practices in Argentina, which is crucial to the country's economy. Klein's contributions reflect a long-standing commitment to enhancing food security and agricultural productivity in the region.

Klein is survived by his wife Mabel Prieto, ten children, and nine grandchildren. His passing marks the end of an era for the Argentine wheat industry, and many who knew him recall his dedication and influence on future generations of agronomists and farmers. His legacy will likely inspire continued innovation in agricultural practices while honoring the traditions he helped establish in Argentine agriculture.
