Christopher Stokowski: The Brother Anderson Cooper Lost

Christopher Stokowski is the younger of two sons Gloria Vanderbilt had with conductor Leopold Stokowski. He was born on January 31, 1952, in New York City. He is the older maternal half-brother of Anderson Cooper, and he has spent most of his adult life outside public view.

That is the short version. The documented version is longer, and it is not the one most biography sites publish. Christopher Stokowski spent nearly four decades not speaking to his mother. The break followed the collapse of his engagement to April Sandmeyer. It also involved his mother's psychiatrist, Dr. Christ L. Zois. He eventually left the country. He lived at his father's farm in England before returning to Vermont and elsewhere in New England. Reconnection with his family came in 2016.

Quick Profile

Who is Christopher Stokowski?

Christopher Stokowski is a Vanderbilt by birth and a Stokowski by parentage. That made him the grandson of railroad heir Reginald Claypoole Vanderbilt. His mother, Gloria Laura Vanderbilt, was born on February 20, 1924. She died on June 17, 2019, aged 95. His father, Leopold Stokowski was among the most recognised orchestral conductors of the twentieth century. He died in 1977.

Christopher is the younger son. His older full brother is Leopold Stanislaus Stokowski, generally known as Stan, who was born on August 22, 1950. The difference between them is two years and nine days.

Both brothers worked in music, following their father. Christopher Stokowski used a pseudonym so he would not trade on the Stokowski name. He also made art, again declining to attach his well-known name. That choice, working privately under another name, appears to have been the pattern of his adult life.

Why was Christopher Stokowski estranged from his mother?

The estrangement began with the end of Christopher Stokowski's engagement to April Sandmeyer and with the involvement of Dr. Christ L. Zois, the psychiatrist treating his mother.

Vanderbilt was grieving after her fourth husband, author Wyatt Emory Cooper, died in January 1978 during open-heart surgery. Her relationship with Zois went well beyond a normal doctor-patient arrangement. She gave him expensive gifts and paid for his vacations. She later discovered he had taken money from her. That contributed to tax evasion problems on her properties.

In 1993, Vanderbilt won a judgment of $1.5 million against Zois and a lawyer. She accused them of preying on her wealth and emotional fragility. That judgment is not mentioned in the documentary about her family.

Sandmeyer, who was reached by Page Six in April 2016, described the psychiatrist's role without going into detail. She said she was just horrified and could not reveal what happened. She said it was very sad and very horrible and had a lot to do with the doctor. She added that Christopher started to become estranged after the incident, and that she would not divulge anything more.

On the wider relationship with her mother, Sandmeyer was warmer. She said Gloria was his best friend and that they were a really loving family. She said everyone treated each other well and with respect. She also said the silence about Christopher came out of love for him.

What happened to Christopher Stokowski after the breakup?

Christopher Stokowski tried to repair the relationship. Sandmeyer rebuffed his attempts to reach her by phone and by letter. After that, he left the country.

He moved to Nether Wallop. It was a farm in England that belonged to his father. When he later returned to the United States, he lived quietly in Vermont and in various New England states. No further detail about Christopher Stokowski's working life or his residence has been reliably published.

This is also where biography sites diverge sharply from the record. Several publish a full name of Leopold Stanislaus Stokowski. That is his brother's name. They also add six siblings, a college, a height, a weight, hair and eye colour, and a large net worth. None of that is supported by any source cited here.

What was said at Carter Vanderbilt Cooper's funeral?

Carter Vanderbilt Cooper died by suicide on July 22, 1988. He was 23. He died by jumping from the family's fourteenth-floor apartment. Gloria Vanderbilt later wrote about it in her 1996 memoir, A Mother's Story.

April Sandmeyer attended Carter's funeral. Christopher did not. That was the moment his mother discovered that the engagement had ended years earlier. She had spent a decade assuming that Christopher and Sandmeyer were still together.

Christopher Stokowski was fifteen years older than Anderson Cooper. No reliable source documents a close relationship between the two. Their fathers also died within a year of each other. Leopold Stokowski died in 1977, and Wyatt Cooper died in 1978.

When did Christopher Stokowski reconcile with his family?

Reconnection came in 2016, after an HBO documentary pushed Christopher Stokowski to act.

Nothing Left Unsaid: Gloria Vanderbilt & Anderson Cooper premiered in April 2016. It was produced and directed by Liz Garbus, and it examined Gloria Vanderbilt's life and her family's history.

The film drew criticism for barely mentioning Christopher. One viewer told Page Six the film glossed over the son. He asked how you live having a son who doesn't want to see you. Stan Stokowski, the eldest son, appeared in the film. Christopher did not.

Sandmeyer, who said she had not seen the film and referred to Gloria as Mrs. Cooper, said she thought the omission was deliberate. She said it was a sensitive topic and that Gloria was too much under Zois's influence at the time.

After the documentary was released, Christopher, Gloria and Anderson Cooper began meeting.

Is Christopher Stokowski married?

There is no confirmed public information on Christopher Stokowski's marital status. April Sandmeyer is the only documented serious relationship. They met in the mid-1970s and were engaged by 1978. The engagement ended, and no marriage followed in any record published since.

What was documented about Christopher Stokowski's career?

Very little, and the little that exists points in a consistent direction.

He and Stan both followed their father into music. Christopher Stokowski's decision to work under a pseudonym was deliberate. He did not want the Stokowski name to stand in front of him. That is the opposite of how the family usually operated.

He also made art. Again he kept his name off it. The pattern was the same in both cases. Christopher Stokowski built a working life that could not be traced back to the name.

Almost nothing else about Christopher Stokowski's professional life has been published. No employer, no institution, no credit and no interview has surfaced in any source reviewed for this profile. That absence matters, because biography sites nonetheless publish specific details about his working life. Those details have no origin.

The one concrete geographic fact on record is where he went. He left the United States after the breakup with Sandmeyer. He lived at his father's farm at Nether Wallop in England. When he came back, he settled in Vermont and elsewhere in New England.

Why do biography sites disagree about Christopher Stokowski?

Because most of them are not reading the sources. They are writing around them.

The clearest example is his name. Several sites list his full name as Leopold Stanislaus Stokowski. That name belongs to his older brother, who was born on August 22, 1950. Christopher is Christopher. The two brothers are frequently merged into one entry.

The same sites publish a net worth and a college Christopher Stokowski is not recorded as attending. None of these appear in the reporting reviewed here.

One site publishes a fictional interview with Christopher, complete with invented questions and invented answers. It presents his imagined responses as if they were quotations from him.

The pattern matters because the real record contains genuine drama. It contains a broken engagement, a psychiatrist who took his mother's money, and a funeral Christopher did not attend.

Why is almost nothing known about Christopher Stokowski's daily life?

Because he arranged it that way, and because the people who could describe it have mostly stayed silent.

The available evidence points one way. He worked under a pseudonym. He kept his name off his art. He left the country rather than stay near the family. He lived in rural New England. He did not take up the public roles the Vanderbilt name could have offered.

None of this points to an unhappy man. It points to a deliberate one. Sandmeyer's account of the years before the breakup describes a close and respectful household. Her description of the silence afterwards is one of a family that stopped speaking, not one that fell apart.

What the record does not contain is the sort of detail that makes a biography readable. There is no daily routine, no home, no marriage and no children in the sources reviewed here. There is no interview on his own terms either.

That is why so much of what circulates online about Christopher Stokowski is invented. A gap in the record invites filling, and the fill usually arrives with the same confidence as the verified material. It should not be read as equivalent to it.

Other family-member profiles include Pablo Huston, John Huston's adopted son, and Samaya White, Jaleel White's daughter.

His older brother is covered here: Leopold Stanislaus Stokowski, Gloria Vanderbilt's eldest son.
