**Hans Zulliger** (21 February 1893 – 18 October 1965) was a distinguished Swiss educator and psychologist, renowned for his groundbreaking work in developing IQ tests for children. His innovative approach to psychology was deeply influenced by his Human Design as a **Manifesting Generator**, a type known for its dynamic blend of energy and responsiveness. This unique design enabled Zulliger to engage profoundly with his surroundings, allowing him to intuitively respond to the needs of children and the intricate dynamics of play.

From 1930 to 1935, Zulliger pioneered **Spieltherapie** (Play Therapy), a method he meticulously crafted to be “deutungsfrei,” or free from interpretation. This approach is a testament to his **Sacral Inner Authority**, which guided him to trust his gut feelings and instincts when working with young minds. His insights into the character and function of children’s play culminated in his seminal book, *Heilende Kräfte im kindlichen Spiel*, where he eloquently shared his understanding of the healing powers inherent in play.

Zulliger’s Human Design profile as a **4/6** emphasizes his role as a networker and role model, fostering connections that promote learning and personal growth. His **Incarnation Cross**, the **Right Angle Cross of The Sleeping Phoenix** (55/59 | 34/20), symbolizes a transformative journey, highlighting his remarkable ability to rise from challenges and inspire others through his work.

Throughout his life, Zulliger’s channels, including **16-48**, **20-34**, and **27-50**, played a pivotal role in shaping his capacity to communicate effectively, embody nurturing energy, and maintain a profound sense of responsibility for the well-being of children. He was born in Biel, Switzerland, and passed away in Ittigen, leaving behind a lasting legacy that continues to influence the fields of education and psychology. His contributions remain a testament to the power of understanding human behavior through both psychological principles and the lens of Human Design.
