The nine facts most often searched about Peter Hermann tell a consistent story: a German-American actor who built a family and a career with remarkable longevity.

Are Peter Hermann and Mariska Hargitay still together?

Yes — and they’ve been one of Hollywood’s most stable couples for more than two decades. Peter Hermann and Mariska Hargitay married in 2004 after meeting on the set of Law & Order: Special Victims Unit (People magazine (celebrity news authority)). The couple has three children: son August, born in 2006, and twins Amaya and Andrew, born in 2011 via surrogate (People).

Is Peter Hermann still married to Mariska Hargitay?

Yes, as of 2025 the couple remains married. There have been no public reports of separation or divorce. Both frequently appear together at red-carpet events and charity functions, most recently supporting Hargitay’s Joyful Heart Foundation (Apple TV (streaming platform)).

The implication: Hermann’s private family life has been a consistent anchor, allowing him to take on diverse acting roles without the tabloid distraction that plagues many celebrities.

What ethnicity is Peter Hermann?

Peter Hermann is of German ethnicity. He was born in New York City but lived in Germany until the age of 10 (IMDb (filmography database)). His father was a German businessman, and Hermann reportedly speaks four languages: English, German, Spanish, and French (IMDb biography).

Is Peter Hermann of German descent?

Yes. The actor’s full birth name is Karl Peter Frederic Albert Hermann, reflecting his German heritage (IMDb biography). He attended school in Germany before returning to the U.S. and later teaching ESL and special education through Teach For America (IMDb biography).

The pattern: Hermann’s bilingual upbringing gave him a cultural fluency that may have informed his ability to play a wide range of characters, from a German-speaking businessman in The Post to a New York book publisher.

How did Mariska Hargitay and Peter Hermann meet?

The classic Hollywood meet-cute: Hermann was a guest star on Law & Order: Special Victims Unit in 2001. He played defense attorney Trevor Langan, opposite Hargitay’s Olivia Benson. The chemistry was immediate, and they began dating soon after (IMDb). They married in a private ceremony in 2004 (Apple TV).

When did Peter Hermann and Mariska Hargitay start dating?

According to published accounts, their relationship began shortly after filming the 2001 episode. Hargitay later told People that she was immediately taken by Hermann’s height and quiet confidence. The timeline is consistent: they were married three years later.

What this means: The couple’s origin story isn’t just trivia — it’s a case study in how two busy actors can build a life together when they prioritize timing and mutual respect.

What is Peter Hermann’s height?

Peter Hermann stands 6 feet 5 inches (1.96 m) tall (IMDb biography (industry database)). That makes him one of the taller actors on television, noticeably towering over his Younger co-star Sutton Foster (5 ft 5 in) and his wife Mariska Hargitay (5 ft 8 in).

How tall is Peter Hermann compared to other actors?

Hermann’s height is a distinctive feature. He is taller than the average leading man (around 5 ft 10 in). Among his Law & Order colleagues, he stands out — only a few actors like Ice-T (6 ft 2 in) come close. Directors reportedly use camera angles to keep him in frame with shorter co-stars.

The trade-off: Hermann’s height gives him a commanding presence on screen, but it also means he often plays authority figures (lawyers, executives, fathers) rather than everyman roles.

What movies and TV shows has Peter Hermann been in?

Hermann’s filmography spans more than 40 credits across film, television, and stage. Here are the key entries:

Peter Hermann filmography

• TV series: Younger (Charles Brooks, 2015–2021) (People), Law & Order: SVU (Trevor Langan, 2002–2020 recurring) (BroadwayWorld (theatre authority)), Blue Bloods (recurring), Elementary, The Good Wife, Beautiful People (2006), Angela’s Eyes (2006), Guiding Light (1997–1998) (People)
• Films: United 93 (2006), 21 (2008), The Post (2017), Then She Found Me (2007) (Rotten Tomatoes (film review aggregator))
• Broadway: Four stage shows including Love Letters and Noises Off (BroadwayWorld)

Did Peter Hermann appear in Law & Order?

Yes, but primarily in the SVU franchise. His character Trevor Langan appeared in over a dozen episodes of Law & Order: Special Victims Unit between 2002 and 2020 (BroadwayWorld). He also had a small role in the original Law & Order series.

The pattern: Hermann’s career demonstrates a deliberate mix of long-running network TV roles and high-profile film appearances, plus theatre for artistic credibility — a combination that has kept him employable for 25 years.

What is Peter Hermann’s net worth?

Estimates place Peter Hermann’s net worth around $15 million (All American Speakers (speaker bureau)). This figure is based on his acting salaries, writing earnings from his children’s book, and endorsement deals (he is the face of Persil ProClean detergent, though exact payment is not public). By comparison, his wife Mariska Hargitay has a reported net worth of $100 million.

How much money does Peter Hermann have?

The $15 million figure is an estimate from celebrity wealth aggregators. It is not audited. Hermann’s income sources include: TV residuals from Younger and Law & Order reruns; film fees; book royalties; and brand partnerships. He also works as a producer on some projects.

The catch: Net worth estimates for actors are notoriously unreliable, especially for someone like Hermann who keeps his finances private. The $15 million figure should be treated as a rough floor, not a precise number.
