Dividend-paying companies are an oasis in the desert of underperforming stocks. They offer solid payouts today and the promise of capital gains tomorrow. According to a study by Ibbotson, reinvested dividends made up about 40% of total stock returns from 1926 to 2006. In fact, dividend investing is so appealing that superinvestor Warren Buffett has made dividend stocks a significant component of his portfolio.

When searching for great dividend stocks, it makes a lot of sense to start with companies that have been playing the dividend game the longest. Standard & Poor's has culled the dividend winners from the also-rans in a list it calls the "dividend aristocrats."

Let's examine the top dividend aristocrats by yield in the Pharmaceuticals, Biotechnology, and Life Sciences industry. For context, I've also included their five-year annualized dividend growth rate.

In its annual reconstitution of the Dividend Aristocrats index recently, S&P eliminated Eli Lilly (NYSE: LLY) from the portfolio. Although Lilly hasn't raised its payout since early 2009, the stock still offers a fat 5.6% yield.

These aren't formal recommendations -- just ideas for your own further research. Still, they could give you a great start toward finding companies capable of paying rising dividends for a quarter-century or more. S&P just announced its dividend aristocrats for 2011, and you can see the top yielders for yourself.
