"The trees were produced from lichen, a kind of dried fungus, imported from Norway," said Dr. Kramer. "Over time, they expanded to producing plastic scenic parts for model railroading such as crossing signs, street lamps, buildings and other products to make train layouts more authentic."

Mr. Kramer went to Japan in 1955 to develop manufacturing ties. He expanded his contacts to plants in Taiwan, Hong Kong and China.

"He explained that he was struck by the privation that remained in Japan just a decade after World War II," his son said. "His skill was dealing with the people there. He did the legwork and rarely talked about it. For all his travels in Asia, he never took a camera."

After using plastic foam to make miniature mountains for train layouts, the Kramer firm started making ice chests.

"By the time the business was sold in 2000, we made 90 percent of the foam ice chests in the country," Dr. Kramer said.

Services were held April 28 in Miami.

In addition to his son, survivors include his companion of 12 years, Florence Cohen; three grandchildren; and three great-granddaughters. His wife of 53 years, the former Doris Goldman, died in 2001. His brother, Lou Kramer, died in 2003.
