=Gutiérrez= (=Juan María=) was born in Buenos Aires. He was a lawyer by profession, but is best known for his writings. Like Sarmiento, he fled to Chile to escape the tyranny of Rosas, and devoted himself to journalism, public education, and the publication of didactic works. In 1846 he was appointed director of the Naval Academy of Valparaíso, introducing during his term very important reforms. From 1845 to 1849 he edited a collection of poems by José Joaquín Olmedo, another collection, entitled _América Poética, El Arauco Domado_ by Pedro de Ona, and textbooks such as _El Lector Americano_, _La Vida de Franklin_, _Elementos de Geometría_. He returned to Argentina in 1852, after Rosas' defeat at the battle of Caseros, lending his efforts to the advancement of education, as he had done in Chile. He was appointed president of the University of Buenos Aires, and entirely revised its obsolete curriculum and faculty. In addition to being one of Argentina's foremost educators, he has the distinction of being her first literary critic of note. Among his works on literary criticism may be mentioned the following: _Artículos Críticos y Literarios_ (1860); _Estudios Biográficos y Críticos sobre Algunos Poetas Sur Americanos Anteriores al Siglo XIX_ (1865); _Apuntes Biográficos de Escritores, Oradores, y Hombres de Estado de la República Argentina_. His style is characterized by correctness and precision. In 1873 he was made president emeritus of the University of Buenos Aires. He died the following year. =Lacasa= (=Pedro=) was born in Buenos Aires in 1810. Early in life he gave up his studies to devote himself to agriculture. When the revolution of 1839 broke out, he took part in it, and rose to the rank of colonel. In 1865 he took part in the war against Paraguay. He died in Jujuy in 1869. His son, Pedro Lacasa, published in 1870 a volume containing his poems, a biography of General Lavalle, and one of General Miguel Soler.
