Giovanni Battista Brocchi

Died 25 Sep 1826 at age 54 (born 18 Feb 1772). Italian geologist who taught natural history at the gymnasium at Brescia (1802-08), then held the post inspector of mines at Milan until 1814. He used his experience organizing the mining industry in Egypt (1822-26). In 1814, he published his major work, Subapennine Fossil Conchology which gave a detailed description of fossil deposits in Italy.Brocchi drew an original analogy that species have births and deaths like individuals. He saw comparisons in the Subapennine fossils with living fauna, but also found contrasts with the extinct fossils described by Lamarck found in the Paris Basin. Though Brocchi’s line of thought was not fully developed, it later influenced Charles Darwin’s conjectures on evolution.«[Also known as Giambattista Brocchi]
