e was born in Uruguay, in the first section of the county of Flores. In February 1935 his professional debut took place on Radio Rossi CX42 of Montevideo where he stayed until 1942 as member of the cast of the radio show Hora Gaucha. By that time he also worked as actor in the plays Tribuna Sonora and in Trampolín de Panorama with the theater company led by Julio Alassio and Mela Paz.

His sobriquet dates back to the 40s when he used to appear with the Luis Altieri Orchestra at the Café Montevideo located on 18 de Julio and Yaguarón. With that aggregation he also sang at the Café Ateneo and on the CX20 and CX30 radio stations. By that period he as well worked as teacher at the Don Orione School until 1945.

The following year he moved to Buenos Aires hired by the impresario of the Teatro Maipo, Mario Fortunato, to join the Miguel Caló Orchestra. Before his departure a party was held to say goodbye to him at the Maroñas horse racetrack which was completely crowded. There was need of fetching chairs and tables from the neighboring barrooms to tend the five thousand attendants.

With Caló he made an intensive tour of South America and Mexico. He also recorded with the accompaniment of the «Guitarras de Magaldi», a guitar group, but unexpectedly, some health problem forced him to return to Montevideo. As soon as he recovered he joined the orchestra led by Miguel Capotillo with which he recorded in the Sondor studios. In the 50s he came back to Buenos Aires and sang at the most important radio stations and venues of the Buenos Aires capital city.

Thereafter, along with maestro Donato Racciatti, he made tours of Brazil and Argentina and, again, was hired by Miguel Caló to tour all the American continent. In 1966 he recorded for the Oro label with the tango orchestra headed by Orlando Romanelli and, for Sondor records, with the tango orchestra of Miguel Ángel Piestrafesa and the one fronted by Tito Ferro, the latter known as Los Ases.

Between 1969 and 1971 he was member of the cast of the Argentine television program: Grandes Valores del Tango aired by Channel 13.

In 1972 he joined the orchestra headed by Rogelio Coll —Garabito—, with which he again recorded for Sondor records.

In Buenos Aires, in 1980, he was awarded the title of «El Decano de los Cantores de Tango» (Dean of Tango Singers) and was paid homage in numerous venues, on radio and television.

When maestro Coll died in 1988, Soler took over the leadership of the orchestra and appeared throughout Uruguay, Buenos Aires and the southern area of Brazil.

In 2003 he was honored by all the tango institutions of Uruguay and, the following year he was appointed honorable partner of SUDEI (Sociedad Uruguaya de Artistas e Intérpretes).

Throughout his extensive career he shared the spotlight with figures of the level of Roberto Goyeneche, Alberto Marino, Alberto Castillo, Juan D'Arienzo, Aníbal Troilo, Carlos Di Sarli, Alfredo De Angelis, Jorge Casal, Jorge Vidal, Mariano Mores, Celia Cruz, Tito Lusiardo, Tita Merello, Nina Miranda , Lágrima Ríos, Alberto Mastra, Osvaldo Pugliese, Romeo Gavioli, Miguel Villasboas and many more.

This true maestro of popular song is an example of life. At age 85 he returned to the recording studios with a new recorded release that combines new tunes with classics of his songbook. He is still going strong with his tango quintet lined up by: Luis Etchebarne (piano), Héctor Blengio (bandoneon), Leonel Gasso (bandoneon), Eduardo Rubial (violin) and Vicente Martínez (double bass).

Despite his age he went on appearing in his country while keeping all the artistic and vocal attributes that were his features throughout his career.

In 2008 he was appointed «Ciudadano ilustre de Montevideo» (Illustrious Citizen of Montevideo) by Municipal Council of that city, but he died two weeks before being awarded.
