Rebecca Gratz to Benjamin Gratz - April 20, [1863]

After the recent deaths of her brother Jo and sister Richea, Rebecca writes to her sister-in-law Ann, deeply mourning her losses and reflecting on the death of her brother Jacob.

Rebecca writes to her sister-in-law Maria, answering her questions about Jewish religion, and warns her of false myths about Judaism. She also gives updates on the health, travels, and marriage plans of family and friends.

Rebecca writes her friend Maria with news of Eliza, Maria's sister, and her medical treatment. She also details the scandal around a renowned cleryman and his intended marriage to a much younger woman.

Writing to her sister-in-law Ann, Rebecca announces the birth of her niece Sara's daughter, Lizzie, gives updates on family and friends, and discusses her readings, including Charles Dickens.

This document consists of three pages. The first page features a computer-generated diagram of a snowflake-like chemical structure, presented in pink lines on a light background. The second page provides a printed explanation of this visual element, identifying it as the crystal structure of their first spherand. It states that the compound was specifically designed to bind Li+ and Na+ cations while rejecting all others, confirming its success. The third page is a handwritten letter from Don Cram to Professor Wiesel. In the letter, Cram expresses gratitude for a telegram of congratulations and an invitation to a meeting in Paris. He apologizes for his inability to attend, citing health reasons (recovering from shingles), and concludes by wishing Professor Wiesel a fine meeting and a happy 1988.
