Previous works on educators who built the field of early childhood education do not provide the researcher with primary and secondary sources or information on multicultural educators, nor do they discuss some of the more current leading educators.

The biographies provide a personal perspective from which to view the primary sources. The biographies are arranged in alphabetical order followed by the primary sources arranged in chronological order.
