Background: Frederick Law Olmsted (April 26, 1822 - August 28, 1903) was an American landscape architect, journalist, social critic, and public administrator. He is popularly considered to be the father of American landscape architecture. Olmsted was famous for co-designing many well-known urban parks with his senior partner Calvert Vaux, including Central Park in New York City. Other projects that Olmsted was involved in include the country's first and oldest coordinated system of public parks and parkways in Buffalo, New York; the country's oldest state park, the Niagara Reservation in Niagara Falls, New York; one of the first planned communities in the United States, Riverside, Illinois; Mount Royal Park in Montreal, Quebec; the Emerald Necklace in Boston, Massachusetts; Highland Park in Rochester, New York; Belle Isle Park, in the Detroit River for Detroit, Michigan; the Grand Necklace of Parks in Milwaukee, Wisconsin; Cherokee Park and entire parks and parkway system in Louisville, Kentucky; the 735-acre (297 ha) Forest Park in Springfield, Massachusetts, featuring America's first public "wading pool"; the George Washington Vanderbilt II Biltmore Estate in Asheville, North Carolina; the master plans for the University of California, Berkeley, the University of Maine, and Stanford University near Palo Alto, California, as well as for The Lawrenceville School; and Montebello Park in St. Catharines, Ontario.
Context: Olmsted was an important early leader of the conservation movement in the United States. An expert on California, he was likely one of the gentlemen "of fortune, of taste and of refinement" who proposed, through Senator John Conness, that Congress designate Yosemite Valley and Mariposa Big Tree Grove as public reserves. This was the first land set aside by Congress for public use. Olmsted served a one-year appointment on the Board of Commissioner of the state reserve, and his 1865 report to Congress on the board's recommendations laid an ethical framework for the government to reserve public lands, to protect their "value to posterity". He described the "sublime" and "stately" landscape, emphasizing that the value of the landscape was not in any one individual waterfall, cliff, or tree, but in the "miles of scenery where cliffs of awful height and rocks of vast magnitude and of varied and exquisite coloring, are banked and fringed and draped and shadowed by the tender foliage of noble and lovely trees and bushes, reflected from the most placid pools, and associated with the most tranquil meadows, the most playful streams, and every variety of soft and peaceful pastoral beauty." In the 1880s he was active in efforts to conserve the natural wonders of Niagara Falls, threatened with industrialization by the building of electrical power plants. At the same time, he campaigned to preserve the Adirondack region in upstate New York. He was one of the founders of the American Society of Landscape Architects in 1898. Olmsted was also known to oppose park projects on conservationist grounds. In 1891, Olmsted refused to develop a plan for Presque Isle near Marquette, Michigan, saying that it "should not be marred by the intrusion of artificial objects."
Question: Did he join any association for conservation ?
Answer: He was one of the founders of the American Society of Landscape Architects in 1898.

Background: Clinton Richard Dawkins (born 26 March 1941) is an English ethologist, evolutionary biologist, and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008. Dawkins first came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centred view of evolution and introduced the term, meme. With his book The Extended Phenotype (1982), he introduced into evolutionary biology the influential concept that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment.
Context: In his book, The Selfish Gene, Dawkins coined the word meme (the behavioural equivalent of a gene) as a way to encourage readers to think about how Darwinian principles might be extended beyond the realm of genes. It was intended as an extension of his "replicators" argument, but it took on a life of its own in the hands of other authors, such as Daniel Dennett and Susan Blackmore. These popularisations then led to the emergence of memetics, a field from which Dawkins has distanced himself. Dawkins's meme refers to any cultural entity that an observer might consider a replicator of a certain idea or set of ideas. He hypothesised that people could view many cultural entities as capable of such replication, generally through communication and contact with humans, who have evolved as efficient (although not perfect) copiers of information and behaviour. Because memes are not always copied perfectly, they might become refined, combined, or otherwise modified with other ideas; this results in new memes, which may themselves prove more or less efficient replicators than their predecessors, thus providing a framework for a hypothesis of cultural evolution based on memes, a notion that is analogous to the theory of biological evolution based on genes. Although Dawkins invented the term meme, he has not claimed that the idea was entirely novel, and there have been other expressions for similar ideas in the past. For instance, John Laurent has suggested that the term may have derived from the work of the little-known German biologist Richard Semon. In 1904, Semon published Die Mneme (which appeared in English in 1924 as The Mneme). This book discusses the cultural transmission of experiences, with insights parallel to those of Dawkins. Laurent also found the term, mneme, used in Maurice Maeterlinck's The Life of the White Ant (1926), and has highlighted the similarities to Dawkins's concept. James Gleick describes Dawkins's concept of the meme as "his most famous memorable invention, far more influential than his selfish genes or his later proselytising against religiosity".
