New York 400 in 2025


The unique character of New York City, originally New Amsterdam, was shaped by the legacy of the entrepreneurial and (relatively) tolerant culture of the 17th century Dutch Republic. Today, the Henry Hudson 500 Foundation celebrates Dutch-American history and future by organizing projects and events in the context of three shared core values: freedom, entrepreneurial spirit, and inclusion, which we believe to be the foundation for successful and thriving societies, then and now.

In ‘1609: the Forgotten History of Hudson, Amsterdam and New York’ Russell Shorto and Geert Mak explore how these cities changed the world.

The Job Swap Amsterdam – New York
September 2025

The Job Swap is set to become one of the pivotal 2025 commemorative events in both NYC and Amsterdam.
The program is a unique experiment in transatlantic cooperation. 30 Citizens of New York and Amsterdam of every background and means of employment are invited to participate in trading places for a week, to deliver new perspectives and reveal profound connections between residents of the two cities: from garbage collectors in Central Park or Vondelpark to the Mayor, and from waitresses, architects, librarians, refugees, fire fighters and park rangers. The Job Swap is a concentrated effort in September 2025. The appr. 15 Dutch Job-swappers will work for 5 days in NYC by mid-June,  the New Yorkers come to Amsterdam late September. 

Throughout the exchange, participants will be closely followed on their own socials, and  by  local, regional and national media (e.g, NY1, AT5, SBS6, de Volkskrant, New York Times).

Origins – Light on New Yorks Founders
2024 – 2025

2025 marks the 400-year anniversary of New York, founded in 1625 as New Amsterdam.
In 1643, when barely 500 people called New Amsterdam home, a visiting Jesuit priest reported that already 18 languages were spoken. The major groups included Dutch, Germans, English, Africans, Scandinavians, French, and Jewish. Free trade and an immigrant culture took root in New Amsterdam, and then in New York, the first multiethnic New World city. 
Was it that good from the get go? Obviously not. Gays were prosecuted, most men of influence relied on enslaved people, ordinary sailors died like flies. But it was the birth of modern – the beginning of a free, tolerant, entrepreneurial and inclusive society.
Starting in 2024 visual artists will be commissioned to create artistic interpretations of New York’s founders in a variety of visual arts forms: video, animation, projection, hologram, light sculpture, painting or performance. The founder will be represented by an artist with ties to their country of Origin: the Netherlands, Belgium, France, England, Germany, Dominican Republic, Morocco, West coast of Africa, Poland, as well as an American Indian.
The goal is for the lives and legacies of 16 men and women who founded NYC, in their artistic interpretation, to inspire us 21st century city- dwellers.

Jan Rodriquez, Dominican Republic, one of the first non-native American settlers or Manhattan.
The Rapalje Children, 18th century off spring of Catalina Tricot (France) en Joris Rapalje (Wallonia). Joris and Catalina - illiterate teenagers when they sailed to New Amsterdam in 1624 - had 11 children in the New World. It is estimated that over 1,000,000 Americans descend from this fierce couple.
Manuel de Gerrit de Reus. When in 1641 the slave Jan Premero was murdered, eight slaves, including Giant Manuel, made a group confession to the murder. They drew lots to decide which of the eight would be hanged and Giant Manuel was left with the short straw. The gallows was prepared. A double noose was placed around Manuel’s neck. He climbed the steps and the hangman pushed him off the edge. Both nooses broke, Manuel fell safely to the ground. The crowd called for mercy: this had to be a sign from God. Manuel was set free. In 1644, no longer enslaved, Manuel de Gerrit de Reus was granted about 12 acres of land near the present Washington Square Park.

United We Stand – Een Draght Mackt Maght

The Borough of Brooklyn’s Seal is designed in 17th century Dutch: ‘Een Draght Mackt Maght’, or ‘United we Stand’ and ‘E pluribus Unum’ in the ‘Great Seal of the United States’.  

Today we face disunity internally on both sides of the Atlantic, and between Europe, the USA, China and other countries.  In view of the many global challenges this multidisciplinary art-project highlights unity and common good, offering a bridge between the international forest of bubbles. We ask dancers, designers, writers, painters, filmmakers and other artists from all over the world to come up with ideas that inspire the world to come together.

Performances are set for mid-June 2025 at the St. Marks in the Bowery-church (downtown-Manhattan), and end of September in Amsterdam.

“The Amsterdam 750 expedition (Amsterdam 2019 – 2020)

With the Amsterdam City Archives and Shipping Company “De Nederlanden” we organized a chain of exiting 4-hour expeditions :
– a historic vessel sailed for 2,5 hours along Amsterdam’s canals, where a spirited guide told 11 stories about the cities’ 750-year history on the spots where it happened. How Amsterdam, and later New Amsterdam/NYC, became such highly successful, diverse and progressive cities. 
– a visit to the treasure vault of the Amsterdam City Archives.

The chain of expeditions was interrupted by Corona – but we’ll pick up where we left off pretty soon.

Projects in 2009

2009 was the 400-year anniversary of Henry Hudson dropping anchor near Manhatten.  From the ship’s log, September 11, 1609: then we anchored and saw it was a very fine harbour for all winds’. The Henry Hudson 400 Foundation, then organized in both Amsterdam and New York,  produced several major events and has also inspired many groups to plan exhibitions and programs. Our foundation celebrated the venerable bonds between our two countries and our mutual passion for trade, freedom and diversity.
