His grandfather was the physician and sculptor Raphael Chamizer. Chamizer holds an MA in Social Sciences from Tel Aviv University (1978).

Aviation career 
During his military service, Chamizer was a helicopter pilot. After discharge from the Israel Defense Forces, he became a commercial pilot with Arkia Airlines and a pioneer in Israel's fledgling micro-aviation industry.

Media career

Chamizer was a newspaper columnist, radio presenter for Galei Tshahal and a TV host.  With Zeev Aner, he produced hundreds of nationwide treasure hunt games. He had a daily spot on Razi Barkai and Shelly Yachimovich's radio show, "Hakol Diburim" (1990-1997). The show was broadcast on the Reshet Bet radio channel, where Chamizer presented a featured item called "Chidat Chamizer" (Chamizer's riddle). His riddles were based on imagination and associative thinking rather than general knowledge. The riddles proved challenging to solve and required ‘entering the mind’ of Chamizer to identify and decoding his personal associations.

The prize for solving the riddles increased every day and often amounted to substantial sums of money, thus attracting a large audience. In its seven years on air, the percentage share of listeners increased to 17%,  making him one of the most innovative contributors in radio. Chamizer went on to produce TV game shows, including "Otzar Hanegev", "Yemei Eden BaGalil", "Yovel La’Medina", "Treasures of One Hundred Years of Zionism", "Treasures of World Cup Football", "Treasures of Israel at 60".

He returned to radio in 2004 with a new game show called The "Chamizer Sentence", which offered the highest individual prize awarded in the history of Israeli radio game shows- NIS 240,000. In 2009, Chamizer produced the VOD Treasure for HOT TV, and in 2010, he produced The Treasure of the Century, celebrating 100 years of the Kibbutz Movement in Israel, followed by the New Israel Defense Force Quiz in 2011.

Local culture
For decades Chamizer inspired Israelis to connect en-masse with opportunities for informal study via riddles, puzzles, games, nationwide treasure hunts and innovative educational projects. His surname – Chamizer – has become synonymous among Israelis with any riddle or intellectual challenge that requires wit, imagination and creativity to solve, and it has entered Hebrew slang as a verb, often conjugated playfully to describe the solving of sophisticated riddles.

Educational projects 

Chamizer developed the "Teaching through Riddles" educational method, where imaginative-associative riddles characterized by playful wit, wild leaps of imagination and outlandish word association became part of the approved national teaching curriculum in Israeli schools. To date, over half a million students have taken an active part in projects based around Chamizer riddles.

Chamizer sees his riddles as tools for encouraging inventive thinking. He explains the purpose of the method as follows: "The imaginative-associative riddle, like many of life’s problems, has endless solutions. Therefore, finding the correct approach to solving one, offers a perfect simulation for other life challenges that demand a creative input."

The method lends legitimacy to unconventional thinking and unmediated means, stimulating curiosity, creativity, enthusiasm and competitiveness. The coveted cash prize goes to the player who manages to "enter the riddler’s head," but much credit is also given for improvisation, initiative, creative thinking, teamwork, leadership, focus, openness, self-confidence and courage – and these are the qualities that truly matter. In his words: "My aim is to instill an alternative way of acquiring study skills and assimilating knowledge."

In 2010, Chamizer established the National Riddle Archive, a dynamic online database of imaginative-associative riddles) in association with The Kibbutzim College of Education and the Teachers' Union in Israel. Designed to be used as a teaching resource, facilitating both formal and informal learning, the archive is aimed at professional educators and linked to study topics outlined in the national curriculum.
