Spencer Ferguson Silver (born 1941) is an American chemist who, together with Arthur Fry, invented Post-it notes in 1970.

Silver was born in San Antonio, Texas. He majored in chemistry at Arizona State University, earning a B.S. in 1962, then earned a doctorate in organic chemistry from the University of Colorado in 1966, before taking a position as a Senior Chemist in 3M's Central Research Labs.

Silver is now named on over 20 US patents; but his most significant invention was not an immediate success. In 1968, Silver developed a high-quality but "low-tack" adhesive, made of tiny, indestructible acrylic spheres that would stick only where they were tangent to a given surface, rather than flat up against it. As a result, the adhesive's grip was strong enough to hold papers together, but weak enough to allow the papers to be pulled apart again without being torn. More importantly, the adhesive could be used again and again.

Silver wanted to market the adhesive as a spray, or as a surface for bulletin boards on which temporary notices could be easily posted and then removed. Over the next five years, Silver tried to interest his colleagues at 3M, informally and in presentations. A marketable form of the product proved elusive however, until Arthur Fry attended one of Silver's seminars.

Sean Kingston (born Kisean Anderson; February 3, 1990) is a Jamaican-American singer. He pursued a music career and debuted in 2007 with the album Sean Kingston.

Kingston was born on February 3, 1990, in Miami, Florida and moved to Kingston, Jamaica when he was six. He attended high school in Ocho Rios. His grandfather was the noted Jamaican reggae producer Lawrence Lindo, who worked under the stage name Jack Ruby. At age 11, Kingston spent 3 weeks in jail for breaking and entering, and Kingston lived in a car while his mother was incarcerated for identity theft.

Sean Kingston was discovered through MySpace by Tommy Rotem at Beluga Heights, and signed to the label in a partnership deal with Sony. Beluga is a label notable for its focus on discovering and developing artists. In an interview with HitQuarters label head and producer J.R. Rotem described this process with regards to Kingston:

"Sean Kingston was a rapper when we found him and it was a development process to get him more melodic. At Beluga we essentially refine the talent so that it's more of a marketable product."
