In the 50 years that have passed since Alfred Latka's death in 1949 his
position as the father of mathematical demography has been secure. With
his first demographic papers in 1907 and 1911 (the latter co- authored
with F. R. Sharpe) he laid the foundations for stable population theory,
and over the next decades both largely completed it and found convenient
mathematical approximations that gave it practical applica- tions. Since
his time, the field has moved in several directions he did not foresee,
but in the main it is still his. Despite Latka's stature, however, the
reader still needs to hunt through the old journals to locate his
principal works. As yet no exten- sive collections of his papers are in
print, and for his part he never as- sembled his contributions into a
single volume in English. He did so in French, in the two part Theorie
Analytique des Associations Biologiques (1934, 1939). Drawing on his
Elements of Physical Biology (1925) and most of his mathematical papers,
Latka offered French readers insights into his biological thought and a
concise and mathematically accessible summary of what he called recent
contributions in demographic analy- sis. We would be accurate in also
calling it Latka's contributions in demographic analysis.
