Most people recognize the name Wernher von Braun. He helped shape modern rocketry and played a central role in the American space program. But very few people know anything about his son, Peter Constantine von Braun — a private individual whose name turns up mainly in genealogy searches tied to one of the twentieth century’s most complicated scientific figures.
This article covers what public records actually confirm about Peter: his name, birth, death, parents, and siblings. It also explains why so little information exists about him personally, and how to tell verified facts apart from claims repeated across secondary websites.
The Name Itself — “Peter Constantin” or “Peter Constantine”?
If you have searched for Peter online, you may have noticed the spelling varies depending on where you look. Genealogy records on FamilySearch use “Peter Constantin von Braun.” Many other pages use “Peter Constantine von Braun,” and some introduce further misspellings like “Constatine” or “Constatin.”
All of these refer to the same person — Wernher von Braun’s only son. The FamilySearch record (identified by the code LJTM-6FK) is the most clearly documented source available, so “Peter Constantin” is the better-supported spelling. That said, both forms are widely used online, and knowing both helps when evaluating search results you may have already encountered.
Birth, Death, and the Basic Public Record
According to the FamilySearch record, Peter Constantin von Braun was born on June 2, 1960, in Alexandria, Virginia. The same record places his death in 2002 in London, England, making him 42 years old at the time.
A few secondary sources offer slightly different birth-date details. June 2, 1960, is the date listed by the strongest available source, so that is what should be treated as accurate. The conflicting versions come from weaker, less documented pages and should not be given equal weight.
No public cause of death has been documented, and it would not be appropriate to speculate about it here. What the record does confirm is that he died relatively young, and that his life was spent largely outside of the public eye.
His birth in Alexandria, Virginia, is worth noting for context. By 1960, Wernher von Braun was already deeply embedded in American scientific and public life. Peter came into the world at the height of the space-race era, born into a family that was, in many ways, at the center of it.
His Parents — Wernher von Braun and Maria von Quistorp
Peter’s father was Wernher Maximilian Magnus von Braun, born in 1912 in Germany and died in 1977 in the United States. He is one of the most recognized figures in the history of rocketry and space exploration.
Wernher von Braun’s career had two very distinct chapters. The first was in Germany, where he was a leading engineer behind the V-2 rocket program during World War II. That program used forced labor under brutal conditions, and thousands of people died as a result. This part of his history is well documented and cannot be separated from his biography.
The second chapter began after the war, when Wernher was brought to the United States as part of Operation Paperclip. He became a key figure at NASA and played a foundational role in developing the Saturn V launch vehicle — the rocket that carried astronauts to the moon during the Apollo missions. He was celebrated publicly and was even the subject of a Disney television series in the 1950s.
Peter’s mother was Maria Irmengard Emmy Luise Gisela von Quistorp, generally known as Maria Luise von Quistorp. Wernher and Maria married in 1947, shortly after the war, as the family’s American chapter was beginning. FamilySearch confirms the marriage and lists their children.
Peter’s Siblings and His Place in the Family
Wernher and Maria had three children together. Peter had two sisters: Iris Careen von Braun and Margrit Cécile von Braun. Margrit is listed in records as born in 1952, making Peter the youngest of the three and the only son.
His birth in 1960 came fairly late in Wernher’s life and career. By that point, Wernher was nearly fifty years old and had already achieved significant recognition in the United States. Peter grew up in a household with an internationally known father, though what that experience was like on a personal level is not part of the public record.
The fact that he was the only son is one reason his name appears so frequently in genealogy and family-history searches. Searches for “Wernher von Braun’s children” or “Wernher von Braun’s son” naturally surface Peter’s name, even though he was not a public figure himself.
What Is and Isn’t Known About Peter’s Personal Life?
Here is where the record becomes thin. Direct biographical information about Peter is limited, and public sources do not provide a reliable, detailed account of his education, career, or personal relationships.
One secondary family page — not an institutional biography — claims that Peter served as a member of the Greenwich, Connecticut, board of education and worked as a real-estate salesperson. These details are worth mentioning because they appear in searches, but they should be treated as reported rather than confirmed. The source does not provide strong primary documentation for those claims.
Some other websites suggest career details that are either vague or unsupported by any credible primary source. The research behind this article specifically flags those claims as unreliable, so they are not repeated here.
What can be said clearly is this: Peter was a private person. His name is searchable because of his father’s fame, not because he sought public attention or built a public profile of his own. That distinction matters when evaluating what you find online.
Why So Little Information Exists?
Children of famous people are often well documented in genealogy databases simply because researchers trace family trees. That documentation does not mean the child was themselves a celebrity or public figure.
Peter’s situation is a good example of this. His birth record, death record, parentage, and sibling relationships are findable because of who his father was. But his own life — his choices, his work, his relationships — largely stayed private. That is not unusual, and it should not be treated as suspicious or mysterious.
For readers who want to understand the broader family and historical context, resources like NewBusinessDesk cover public figures and family histories in a way that separates documented fact from online speculation.
It is also worth being careful about genealogy websites more broadly. A family-tree entry created by a volunteer contributor is not the same as a verified institutional record. FamilySearch records are more structured than many open-submission genealogy platforms, but even they can reflect errors that have been copied from one source to another. The best approach is to note what the strongest available source says and be honest about where uncertainty remains.
Separating What We Know From What Gets Repeated
To summarize what is actually supported by reliable sources:
- Peter Constantin von Braun was born on June 2, 1960, in Alexandria, Virginia.
- He died in 2002 in London, England, at age 42.
- His father was Wernher Maximilian Magnus von Braun (1912–1977).
- His mother was Maria Irmengard Emmy Luise Gisela von Quistorp.
- He had two sisters: Iris Careen von Braun and Margrit Cécile von Braun.
- He was Wernher von Braun’s only son.
What is not confirmed by reliable sources includes details about his specific career, education, personal relationships, or the circumstances of his death. Claims about those topics appear on low-quality secondary pages and should not be treated as fact.
A Private Life Connected to a Very Public Name
Peter Constantin von Braun lived and died without seeking or receiving the kind of public attention his father had. He was born into one of the most recognized scientific families of the twentieth century, yet he appears to have led a life that was, by choice or circumstance, largely private.
His father’s legacy is historically complex — celebrated for contributions to space exploration, but also linked to serious ethical failures during the wartime years in Germany. Peter himself cannot be connected to any of that by association. He was a child of that family, not a participant in those events.
What public records give us is a clear but narrow picture: a man born in Virginia in 1960, the youngest child and only son of Wernher and Maria von Braun, who died in London in 2002 at age 42. Beyond that, the documented record is quiet — and that quiet deserves to be respected rather than filled in with guesswork.
