Friederike prefers to keep her privacy. I can say, however, that she's a terrific dancer and wonderful person.
Larry was born in Tennessee, raised in Texas, and moved to Los Angeles in 1982 to work for NASA's Jet Propulsion Laboratory. He is a software engineer but also has a degree in film/TV production. He learned Rock and Roll and Country-Western dancing in the early 60s and Disco dancing in the late 60s, taking courses in Modern and Jazz Dance while in college in the hopes of becoming a disco king. Later he took up American Ballroom and Latin dancing.
In 1989 he took a Salsa course at a studio where Argentine tango was taught. He was instantly hooked on tango and began taking two lessons each week from two different teaching teams. He took lessons from every resident and visiting teacher in Los Angeles for several years, ocasionally traveling to San Francisco when interesting visiting teachers came there but not LA. He attended the First and Fifth Stanford Tango Weeks. Not content with that, he has read books on Argentine tango dancing and music, Argentine history and politics, and more general books on dance physics, physiology, notation, and choreography. He was a frequent contributor for a long time to the TANGO_L Internet discussion group - until someone pointed out to him that some people actually get paid for writing. Since then he's been working to become a professional writer.
In 2000 he was finally able to visit Buenos Aires, which he describes in "Nine Days in Argentina - a Tango Diary", an expansion of reports sent to TANGO-L. He plans to return when his Spanish gets good enough for easy conversation, because he found that meeting people was even more fun than dancing.
