爱新觉罗·永瑆生于乾隆十七年二月初七，生母淑嘉皇贵妃金氏(时为嘉贵妃)。永瑆幼工书，高宗爱之，每幸其府第。永瑆嫡福晋富察氏是大学士傅恒之女，永瑆嫡母孝贤皇后侄。嘉庆四年正月，仁宗命在军机处行走，总理户部三库。故事，亲王无领军机者，领军机自永瑆始。二月，仪亲王永璇罢总理吏部，并命永瑆俟军务奏销事毕，不必总理户部。三月，和珅以罪诛，没其园第，赐永瑆。七月，永瑆辞总理户部三库，允之。八月，编修洪亮吉上书永瑆，讥切朝政，永瑆上闻，上治亮吉罪。语在《洪亮吉传》。十月，上谕曰:"自设军机处，无诸王行走。因军务较繁，暂令永瑆入直，究与国家定制未符。罢军机处行走。"永瑆尝闻康熙中内监言其师少时及见董其昌以前三指握管悬腕作书，永瑆广其说，作拨镫法，推论书旨，深得古人用笔之意。上命书 裕陵圣德神功碑，并令自择书迹刻为诒晋斋帖，以手诏为序。刻成，颁赏臣工。
       十八年，林清变起，永瑆在紫禁城内督捕，上嘉其勤劳，免一切处分及未完罚俸。二十四年正月，加其子不入八分辅国公绵{勤心}郡王衔。五月，祭地坛，终献时，赞引误，永瑆依以行礼。上以永瑆年老多病，罢一切差使，不必在内廷行走，於邸第闭门思过，罚亲王半俸十年。绵{勤心}亦罢内大臣，居家侍父。二十五年六月，绵{勤心}卒，赠郡王。有司请谥，以非例斥之，著为令。仁宗崩，有旨免迎谒。语见仪亲王传。十月，命曾孙载锐袭贝勒。道光二年十月，上还自行在，永瑆进食品十六器，以非例却之。三年三月，薨，年七十二，赐银五千治丧，谥曰哲。载锐袭郡王。绵(勤心)及载锐父奕绶并追封如其爵。咸丰九年，薨，谥曰恭。子爱新觉罗·溥庄，袭贝勒，加郡王衔。

对其书法的评价，有杨翰《息柯杂著》谓:"王得窥内府所藏，而自藏又甚富，故书法大备如是，大抵皆从帖中问津，未深究古碑耳。"(清)礼亲王昭梿《啸亭杂录》谓:"永瑆幼时握笔，即波磔成文，少年工赵文敏，又尝见康熙时内监。言其师少时犹及见董文敏用笔。惟以前三指握管，悬腕书之，故王广推其语，作拨灯法。"又说:"永瑆名重一时，士大夫得片纸只字，重若珍宝。论者谓国朝自王若霖(澍)下，一人而已。"《息柯杂著》又谓:"诒晋斋书，素未究心，但知其从赵承旨上溯欧阳率更，虽偶涉诸家，终不离两家宗旨。集卷随手杂临，竟有脱尽町畦，不似本家笔意者。篆、隶亦有法度，盖书非一时，临非一家，不甚经意，而精神所寄，一一浑足，此无意胜于有意也。"
       善收藏。著有《诒晋斋诗文集》及《续集》、《随笔》、《仓龙集》等。《清史稿》卷二百二十一有传。永瑆作为皇族，其书法的成就也得益于眼界宽、收藏广。

       另外，1971年台湾文化图书公司出版了《成亲王书归去来辞》，1986年巴蜀书社出版了《成亲王书竹枝词》。《近代碑帖大观》还收入了《成亲王书多心经》，《楹联墨迹大观》收入了成亲王的《楷书七言联》"青李来禽书旨邃，荔枝卢橘赋才多"。

成哲亲王永瑆，乾隆十七年二月初七出生，其生母为淑嘉皇贵妃金佳氏，封成亲王，嫡福晋为富察氏，大学士傅恒之女，也即其嫡母孝贤纯皇后的亲侄女。据闻永瑆为人刻薄吝啬，富察氏生活艰苦，除了被永瑆没收嫁妆外，又穿粗衣麻布，吃的也是清茶淡粥，堂堂大学士千金，又是皇室福晋，竟然吃不饱，穿不暖。一日永瑆家的马死了，永瑆下令烹马代膳，"是日即不举食，其吝啬也若是"。乾隆帝多次训斥之，永瑆却本性不改，一切如故。故昭梿对永瑆有"天性阴忮、好以权术駇人。持家苛虐，护卫多以非罪斥革。"、"受人欺诈"、"逢迎权要，其上眷稍有衰者，即骂詈之"等劣评。
      虽然品性存疑，但永瑆的书画造诣是被受肯定，与翁方纲、刘墉、铁保并列，是清代皇室书法家。嘉庆四年，命其在军机大臣行走，总理户部三库。二十四年，嘉庆以永瑆年老多病，罢一切差使，毋庸在内廷行走。道光三年三月三十，永瑆薨，年七十二，谥哲，为成哲亲王。
