2. 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. This reference book
provides biographies and bibliographies of selected pre-
modern and modern men and women who have made
significant contributions to early childhood education. 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. Secondary sources are
listed alphabetically according to author and include
obituaries, articles, dissertations, and books.

3. Johann Amos Comenius
is considered the father of modern education. He served as the last
bishop of Unity of the Brethren and became a religious refugee and one
of the earliest champions of universal education, a concept eventually
set forth in his book Didactica Magna. As an educator and theologian, he
led schools and advised governments across Protestant Europe through
the middle of the seventeenth century.
Comenius was the innovator who first introduced pictorial textbooks,
written in native language instead of Latin, applied effective teaching
based on the natural gradual growth from simple to more
comprehensive concepts, supported lifelong learning and development
of logical thinking by moving from dull memorization, presented and
supported the idea of equal opportunity for impoverished children,
opened doors to education for women, and made instruction universal
and practical. Besides his native Bohemian Crown, he lived and worked
in other regions of the Holy Roman Empire, and other countries:
Sweden, the Polish-Lithuanian Commonwealth, Transylvania, England,
the Netherlands and Hungary.

4. John Dewey
The overriding theme of Dewey's works was his profound
belief in democracy, be it in politics, education, or
communication and journalism. As Dewey himself stated in
1888, while still at the University of Michigan, "Democracy
and the one, ultimate, ethical ideal of humanity are to my
mind synonymous.“
Known for his advocacy of democracy, Dewey considered two
fundamental elements—schools and civil society—to be
major topics needing attention and reconstruction to
encourage experimental intelligence and plurality. Dewey
asserted that complete democracy was to be obtained not
just by extending voting rights but also by ensuring that
there exists a fully formed public opinion, accomplished by
communication among citizens, experts, and politicians, with
the latter being accountable for the policies they adopt.

5. John Locke
was an English philosopher and physician, widely regarded as one of the most
influential of Enlightenment thinkers and commonly known as the "Father of
Liberalism". Considered one of the first of the British empiricists, following the tradition
of Sir Francis Bacon, he is equally important to social contract theory. His work greatly
affected the development of epistemology and political philosophy. His writings
influenced Voltaire and Jean-Jacques Rousseau, many Scottish Enlightenment thinkers,
as well as the American revolutionaries. His contributions to classical republicanism and
liberal theory are reflected in the United States Declaration of Independence.
Locke's theory of mind is often cited as the origin of modern conceptions of identity and
the self, figuring prominently in the work of later philosophers such as David Hume,
Rousseau, and Immanuel Kant. Locke was the first to define the self through a continuity
of consciousness. He postulated that, at birth, the mind was a blank slate or tabula rasa.
Contrary to Cartesian philosophy based on pre-existing concepts, he maintained that we
are born without innate ideas, and that knowledge is instead determined only by
experience derived from sense perception. This is now known as empiricism. An
example of Locke's belief in empiricism can be seen in his quote, "whatever I write, as
soon as I discover it not to be true, my hand shall be the forwardest to throw it into the
fire." This shows the ideology of science in his observations in that something must be
capable of being tested repeatedly and that nothing is exempt from being disproven.
Challenging the work of others, Locke is said to have established the method of
introspection, or observing the emotions and behaviours of one’s self.

6. Johann Pestalozzi
was a Swiss pedagogue and educational reformer who
exemplified Romanticism in his approach.
He founded several educational institutions both in German-
and French-speaking regions of Switzerland and wrote many
works explaining his revolutionary modern principles of
education. His motto was "Learning by head, hand and heart".
Thanks to Pestalozzi, illiteracy in 18th-century Switzerland
was overcome almost completely by 1830.

7. Jean Jacques Rousseau
was a Genevan philosopher, writer and composer. Born in Geneva, his political
philosophy influenced the progress of the Enlightenment throughout Europe, as
well as aspects of the French Revolution and the development of modern political
and educational thought.
He befriended fellow philosophy writer Denis Diderot in 1742, and would later
write about Diderot's romantic troubles in his autobiography, Confessions.
His Discourse on Inequality and The Social Contract are cornerstones in modern
political and social thought. Rousseau's sentimental novel Julie, or the New Heloise
(1761) was important to the development of preromanticism and romanticism in
fiction. His Emile, or On Education (1762) is an educational treatise on the place of
the individual in society. Rousseau's autobiographical writings—the posthumously
published Confessions (composed in 1769), which initiated the modern
autobiography, and the unfinished Reveries of a Solitary Walker (composed 1776–
1778)—exemplified the late 18th-century "Age of Sensibility", and featured an
increased focus on subjectivity and introspection that later characterized modern
writing.
During the period of the French Revolution, Rousseau was the most popular of the
philosophers among members of the Jacobin Club. He was interred as a national
hero in the Panthéon in Paris, in 1794, 16 years after his death.

8. Friedrich Froebel
was a German pedagogue, a student of
Pestalozzi, who laid the foundation for modern
education based on the recognition that children
have unique needs and capabilities. He created the
concept of the "kindergarten" and coined the word,
which soon entered the English language as well. He
also developed the educational toys known as
Froebel gifts.

9. Maria Montessori
was an Italian physician and educator best known for
the philosophy of education that bears her name, and
her writing on scientific pedagogy. At an early age,
Montessori broke gender barriers and expectations
when she enrolled in classes at an all-boys technical
school, with hopes of becoming an engineer. She soon
had a change of heart and began medical school at
the University of Rome, where she graduated – with
honors – in 1896. Her educational method is in use
today in many public and private schools throughout
the world.

10. Jean Piaget
was a Swiss psychologist known for his work on child development.
Piaget's theory of cognitive development and epistemological view are
together called "genetic epistemology".
Piaget placed great importance on the education of children. As the
Director of the International Bureau of Education, he declared in 1934 that
"only education is capable of saving our societies from possible collapse,
whether violent, or gradual." His theory of child development is studied in
pre-service education programs. Educators continue to incorporate
constructivist-based strategies.
Piaget created the International Center for Genetic Epistemology in Geneva
in 1955 while on the faculty of the University of Geneva and directed the
Center until his death in 1980. The number of collaborations that its
founding made possible, and their impact, ultimately led to the Center
being referred to in the scholarly literature as "Piaget's factory".
According to Ernst von Glasersfeld, Jean Piaget was "the great pioneer of
the constructivist theory of knowing." However, his ideas did not become
widely popularized until the 1960s. This then led to the emergence of the
study of development as a major sub-discipline in psychology. By the end of
the 20th century, Piaget was second only to B. F. Skinner as the most cited
psychologist of that era.

there are some lesser known but
very influential ones also but I
think these are known as the
pioneers.
