Alexander A. Maximow

Alexander A. Maximow (January 22, 1874-1928), was a Russian-American scientist renowned for his experimental work confirming the unitarian theory of hematopoiesis: all blood cells develop from a common precursor cell.^[1]

Biography

Maximow was born in Russia and earned a degree as a medical doctor from the Imperial Military Academy, Saint Petersburg. Subsequently, he studied for two years in Germany at Freiburg and Berlin. Returning to Saint Petersburg, he served as professor of histology and embryology from 1903 until 1922. From 1922 until his death in 1928, he served as a professor of anatomy at the University of Chicago.

From 1896 until 1902, Maximow authored numerous papers, concerning a variety of histologic problems, which established the background for his future work. In the later stages of his career, Maximow was primarily interested in the blood and the connective tissues. After demonstrating that all blood cells develop from a common precursor cell, Maximow confirmed the unitarian theory of hematopoiesis. His other experimental work provided evidence confirming that lymphocytes of the blood and lymph nodes are undifferentiated cells.

Maximow wrote "the world's most respected textbook in histology," a book that became a standard text for medical students and ran to 12 editions. He also developed and introduced a unitarian theory of hematopoiesis, a theory upon which the modern concept of blood cells' origin and differentiation is based.^[2]

For four years before Maximow's death, fellow histologist William Bloom worked closely with him on the Textbook of Histology. Bloom ultimately completed the work, which was first published in 1930.^[3]
