Final answer:
The specific influencer on American ECE with a Moravian connection isn't detailed in the resources, but the Moravian contribution of emphasizing individual religious experience and piety likely influenced the spiritual aspect of ECE.
Step-by-step explanation:
The influencer on American Early Childhood Education (ECE) with a Moravian connection is not directly cited in the available reference material. However, the Moravians are known for their emphasis on education and community which were characteristics of the Ephrata Cloister in Pennsylvania, one of the earliest communal experiments in the United States founded by Conrad Beissel in the 1730s. The Moravians, being part of the Protestant pietistic movements, influenced American educational practices by stressing individual religious experience and piety over religious rituals and formality, which could be considered as influencing the development of personal, moral, and spiritual aspects of ECE.
