Peter G. Van Alst (1828 – 1900) was a surveyor who helped to build the roads and infrastructure of western Queens.

Van Alst was born in Dutch Kills on May 28, 1828, and was a member of the large extended Van Alst family, a prominent Dutch farming family who moved to the area in the early 1700s and resided there until the 1870s, when they spread out and moved elsewhere. Van Alst received his education at the District School and the Astoria Institute. He apprenticed as a surveyor for a few years, and worked independently until 1872, when the city legislature appointed him to serve as a commissioner, surveying and supervising the construction of several roads in Long Island City, Queens.

In 1874, Van Alst and three fellow Long Island City citizens comprised the First Ward Improvement Commission, which was in charge of raising the grades of Jackson Avenue from Vernon Avenue to the courthouse from three to eight feet, which profoundly affected the daily life of the city. Van Alst’s job consisted primarily of constructing maps, which revealed detailed organizations of street lines, grades, and sewage lines of the Long Island City area.

Henry Gradstein (1905 - 1971) was a Jewish Russian immigrant who taught at New York public schools up until his death in 1971. He lived in Kew Gardens , Queens, for a number of years. In 1971 Gradstein was the principal of Public School 152 Woodside Queens. Prior to this, he had also been principal of Public Schools 5, 14 and 166, all in Queens. Before becoming principal, Gradstein had taught social studies at Central Commercial High School in Manhattan.

Gradstein graduated from City College and Brooklyn Law School. He also served as a lieutenant in the Army Air Force in World War II.

Thomas Rainey (1824-1910) a resident of Ravenswood, Queens, was one of the main contributors to the bridge across the East River between Manhattan and Long Island City. Rainey spent 25 years and much of his fortune on this bridge. The project was initially highly favored by the community, but it lost momentum in the financial Panic of 1873. Due to this, the burden of organizing and refinancing the company fell on him, first as treasurer in 1874, then as president in 1877. However, the project once again lost steam in 1892 . After the consolidation of New York City in 1898, the project gained new momentum and the bridge was finally built at Queens Plaza, a few blocks south of the proposed location. On opening day in 1909, Rainey realized his dream as he crossed the new bridge with Governor Charles Evans Hughes. The new bridge entitled the "The Queensboro Bridge," fulfilled its promise by tying the Borough of Queens into Greater New York. For his efforts, Rainey received a gold medal inscribed “The Father of the Bridge.”

In 1904, the City of New York acquired several acres of waterfront property. The concrete “sea wall,” built where the park meets the East River, was completed in 1912, by which time Rainey had passed away. To honor his public spirit, the city named the property Rainey Park.

From 1968 to 1998, Lynn Gross (d. 1998) was a dedicated advocate for students and parents within the PS 175 community and throughout Queens.

Gross served as the Parents Association President of PS 157 and the president of the Presidents Council of District 28. In 1980, she was elected to the Community School District 28 Board of Education. As a first-time candidate, she emphasized the need for equitable spending with limited resources.

District 28 covered an area from Rego Park to Forest Hills and south to Jamaica. By the late 1980s, Black parents voiced concerns about unequal representation and insufficient attention to issues in schools in the district's southern region. Consequently, efforts were made to diversify the board's composition. In 1993, Shirley Huntley, a longtime active parent leader, ran for the board, asserting that it had failed students in her part of the district; she won. That same year, incumbent board member and former vice president Claudette Gumbs made history as its first Black president.

Racial tensions within the district escalated in 1996 when a white school librarian at PS 80 in South Jamaica allegedly used a racial slur towards a student. Following heated public meetings where Black parents and community members demanded the librarian's dismissal, the board voted to retain her. The dissenting votes all came from the Black board members. Gross and others who voted to keep the librarian expressed disbelief that she had made the remark. This case significantly strained the long-standing friendship and political alliance between Gross and Huntley.

A year later, Schools Chancellor Rudy Crew removed Gross from the board, citing her failure to adhere to new regulations in the hiring process for a new superintendent. Local residents suspected this was retaliation for the librarian incident, as Crew had urged the board to terminate her employment. Huntley, however, maintained that all board members had been informed of the new hiring rules and that Gross had violated them. Despite an initial appeal, the Board of Education upheld her dismissal. She was granted a second appeal opportunity in the spring of 1998.

Gross passed away in December 1998. An obituary from Community School Board 28 lauded her "intelligent and caring leadership, grace, and drive."

PS 175, formerly known as the Annandale Park School, was renamed The Lynn Gross Discovery School in 2000. Joseph Seluga, a former PS 175 Principal, explained that he added "Discovery" to the name because he and Gross had encouraged students to delve deeply into the social sciences.

William Haberle was an active member of the Rosedale community. He was one of the founders of the Rosedale Civic Association. Haberle was serving his second term as president of the association at the time of his death in 1953. One of his main concerns in the community was overcrowding and lack of sufficient schools. At the time (1950s), some children in Rosedale had to attend schools in neighboring communities. To solve this, Haberle fought to have a new elementary school built. The school, P.S. 195, was approved and completed after his death. The Rosedale Civic Association petitioned to have the school named after him to honor his efforts.
