Kaspar Friedrich Wolff was born on April 23, 1733, in Berlin, Germany.

He studied medicine at the University of Halle and later pursued a career as a surgeon.

In 1759, Wolff published his seminal work "Theoria Generationis," where he proposed his theories on embryonic development.

Wolff's theories challenged the prevailing idea of preformation, which held that organisms exist fully formed in miniature within the egg or sperm. Instead, he proposed epigenesis, suggesting that organisms develop gradually from undifferentiated cells.

Wolff conducted detailed observations on the development of embryos in various species, documenting stages of cellular differentiation and organ formation.

He introduced the concept of germ layers—ectoderm, mesoderm, and endoderm—as fundamental layers from which different tissues and organs arise during embryonic development.

Wolff's ideas laid the foundation for modern embryology and developmental biology, influencing subsequent generations of scientists and researchers.

He held academic positions at several universities, including St. Petersburg Academy of Sciences and the University of Gottingen, where he contributed to the advancement of biological sciences.

Known as the "Father of Embryology," Wolff's contributions revolutionized the understanding of how organisms develop from fertilization to adulthood.

His work continues to be celebrated for its profound impact on embryology and developmental biology, shaping scientific inquiry into the origins of life and the mechanisms of growth and differentiation.
