In her own words, Jean Bartelt is "a Queens girl" who has lived almost her entire life in the same Hollis home her German immigrant parents bought in 1935. She has served people of the borough as both teacher and librarian. Ms. Bartelt is active with the Hollis Presbyterian Church and volunteers for the Queens Historical Society and a historical society in Willimantic, Connecticut, where the family has a summer home. Jean Bartelt looks back on how the ethnic makeup of her neighborhood has changed, beginning with two Jewish families moving in in the 1950s. In the 1960s, a real estate company provoked racial panic and many white residents moved out of the area. Now, Jean describes her block as "wonderfully diverse," with Hispanic, Caribbean, white, and Asian residents living side by side. Ms. Bartelt feels technology is the greatest change in her lifetime.
