Who were the colony of Delaware's founders?

The Delaware Colony was founded in 1638 by the explorer Peter Minuit, who hailed from what is modern-day Belgium. He led the first attempt by the Swedish government to establish a colony in North America. At this time, Sweden was a major European power and wanted to project its growing prestige on the international stage by getting involved in the colonial enterprise. Thus was born New Sweden, located on the lower Delaware River. Although the Netherlands had also established colonies in America close to the Swedish settlement, they were militarily weak at that point and so didn't represent a serious threat to the Swedes.
Minuit became the governor of New Sweden, sorting out territorial disputes with Native American tribes and gathering supplies and financial support for the new colony. However, Minuit's tenure as governor didn't last very long. In the same year as New Sweden was founded, he was killed at sea in a hurricane after stopping off in the Caribbean to pick up a consignment of tobacco.
